Basic general education is completed by the Basic State Examination of Graduates, during which the compliance of their knowledge with the requirements of the state educational standard is checked.
The examination of graduates of the 9th grade of general educational organizations is carried out in the form of testing.
The requirements for the level of preparation of graduates in chemistry, specified in the federal component of the state standard for general education, are the basis for the development of control measuring materials for the OGE.
According to these requirements, a certain system of knowledge about inorganic and organic substances, their composition, properties and application is mandatory for assimilation. This system of knowledge, which is based on the Periodic Law and the Periodic Table of Chemical Elements by D.I. Mendeleev, is the invariant core of all general educational programs in chemistry. In the proposed examination work, it was this content that was the basis for the development of control measuring materials.
The purpose of this manual is to acquaint teachers and students with the structure and content of the examination paper, to enable the graduate to independently check his readiness for a new form of examination in chemistry - in the form of testing.

The state final certification of 2019 in chemistry for graduates of the 9th grade of general educational institutions is carried out in order to assess the level of general education of graduates in this discipline. The tasks test knowledge of the following sections of chemistry:

The structure of the atom.
Periodic law and Periodic system of chemical elements D.I. Mendeleev.
The structure of molecules. Chemical bond: covalent (polar and non-polar), ionic, metallic.
Valency of chemical elements. The degree of oxidation of chemical elements.
Simple and complex substances.
Chemical reaction. Conditions and signs of chemical reactions. Chemical equations.
Electrolytes and non-electrolytes. Cations and anions. Electrolytic dissociation of acids, alkalis and salts (medium).
Ion exchange reactions and conditions for their implementation.
Chemical properties of simple substances: metals and non-metals.
Chemical properties of oxides: basic, amphoteric, acidic.
Chemical properties of bases. Chemical properties of acids.
Chemical properties of salts (medium).
Pure substances and mixtures. Rules for safe work in the school laboratory. Chemical pollution of the environment and its consequences.
The degree of oxidation of chemical elements. Oxidizing agent and reducing agent. Redox reactions.
Calculation of the mass fraction of a chemical element in a substance.
Periodic law D.I. Mendeleev.
Initial information about organic substances. Biologically important substances: proteins, fats, carbohydrates.
Determination of the nature of the medium of a solution of acids and alkalis using indicators. Qualitative reactions to ions in solution (chloride, sulfate, carbonation, ammonium ion). Qualitative reactions to gaseous substances (oxygen, hydrogen, carbon dioxide, ammonia).
Chemical properties of simple substances. Chemical properties of complex substances.

Date of passing the OGE in chemistry 2019:
June 4 (Tuesday).

There are no changes in the structure and content of the examination paper in 2019 compared to 2018.

In this section you will find online tests that will help you prepare for passing the OGE (GIA) in chemistry. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in chemistry consists of two parts. The first part contains 19 tasks with a short answer, the second part contains 3 tasks with a detailed answer. In this regard, only the first part (i.e., the first 19 tasks) is presented in this test. According to the current structure of the exam, among these tasks, only 15 answers are offered. However, for the convenience of passing the tests, the site administration decided to offer answers in all tasks. But for tasks in which answer options are not provided by the compilers of real control and measuring materials (KIMs), the number of answer options has been significantly increased in order to bring our test as close as possible to what you will have to face at the end of the school year.

Specification
control measuring materials
to be held in 2017
main state exam
in chemistry

1. Appointment of KIM for OGE- to evaluate the level of general education in chemistry of graduates of the ninth grade of general education organizations for the purpose of the state final certification of graduates. The results of the exam can be used when enrolling students in specialized secondary school classes.

The OGE is conducted in accordance with the Federal Law of the Russian Federation of December 29, 2012 No. 273-FZ “On Education in the Russian Federation”.

2. Documents defining the content of KIM

3. Approaches to the selection of content, the development of the structure of KIM

The development of KIM for the OGE in chemistry was carried out taking into account the following general provisions.

KIM are focused on testing the assimilation of the knowledge system, which is considered as an invariant core of the content of existing chemistry programs for the basic school. In the Federal component of the state educational standard in chemistry, this system of knowledge is presented in the form of requirements for the preparation of graduates.
KIM are designed to provide an opportunity for a differentiated assessment of the training of graduates. For this purpose, the verification of mastering the basic elements of the content of the chemistry course in grades VIII-IX is carried out at three levels of complexity: basic, advanced and high.
The educational material on the basis of which the tasks are built is selected on the basis of its significance for the general educational preparation of graduates of the basic school. At the same time, special attention is paid to those elements of the content that are developed in the course of chemistry of X-XI classes.

4. Connection of the examination model of the OGE with KIM USE

The most important principle taken into account when developing KIM for the OGE is their continuity with the KIM USE, which is due to unified approaches to assessing the educational achievements of students in chemistry in primary and secondary schools.

The implementation of this principle is ensured by: the unity of the requirements for the selection of content, checked by the tasks of the OGE; the similarity of the structures of the examination options for KIM for the OGE and the USE; the use of similar task models, as well as the identity of the assessment systems for tasks of similar types used both in the OGE and in the USE.

5. Characteristics of the structure and content of KIM 1

In 2017, the choice of the executive authorities of the subjects of the Russian Federation that manage in the field of education is offered two models of examination work, in terms of their structure and content of the tasks included in it, similar to the models of examination work in 2014.

Each version of the examination paper consists of two parts.

Part 1 contains 19 tasks with a short answer, including 15 tasks of a basic level of complexity (the serial numbers of these tasks: 1, 2, 3, 4, ... 15) and 4 tasks of an increased level of complexity (the serial numbers of these tasks: 16, 17, 18, 19). For all their differences, the tasks of this part are similar in that the answer to each of them is written briefly in the form of one digit or a sequence of digits (two or three). The sequence of numbers is written in the answer sheet without spaces and other additional characters.

Part 2 depending on the model, the CIM contains 3 or 4 tasks of a high level of complexity, with a detailed answer. The difference between examination models 1 and 2 is in the content and approaches to the implementation of the last tasks of the examination options:

exam model 1 contains task 22, which provides for the implementation of a "thought experiment";
exam model 2 contains tasks 22 and 23, which provide for the implementation of a real chemical experiment.

Tasks are arranged according to the principle of gradual increase in the level of their complexity. The share of tasks of basic, advanced and high levels of complexity in the work was 68, 18 and 14%, respectively.
Table 1 gives a general idea of the number of tasks in each part of the examination paper of models 1 and 2.

..............................

1 Model 1 (M1) corresponds to demo #1; model 2 (M2) - demo version No. 2.
