Who are these tests for?
These materials are intended for schoolchildren preparing for OGE-2018 in chemistry. They can also be used for self-control when studying a school chemistry course. Each one is dedicated to a specific topic that a ninth-grader will meet on the exam. The test number is the number of the corresponding task in the OGE form.
How are subject tests structured?
Will there be other subject tests published on this site?
Undoubtedly! I plan to post tests on 23 topics, 10 tasks each. Stay tuned!
What else is on this site for those preparing for the OGE-2018 in chemistry?
Do you feel like something is missing? Would you like to expand any sections? Need some new materials? Anything that needs to be fixed? Found any errors?
Good luck to everyone preparing for the Unified State Exam and the Unified State Exam!
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). Despite all their differences, the tasks in this part are similar in that the answer to each of them is written briefly in the form of one number or a sequence of numbers (two or three). The sequence of numbers is written on the answer form without spaces or other additional characters.
Part 2, depending on the CMM model, contains 3 or 4 tasks of a high level of complexity, with a detailed answer. The difference between exam models 1 and 2 lies in the content and approaches to completing the last tasks of the exam options:
Examination model 1 contains task 22, which involves performing a “thought experiment”;
Examination model 2 contains tasks 22 and 23, which involve performing laboratory work (a real chemical experiment).
Scale for converting points to grades:
"2"– from 0 to 8
"3"– from 9 to 17
"4"– from 18 to 26
"5"– from 27 to 34
System for assessing the performance of individual tasks and the examination work as a whole
Correct completion of each of tasks 1–15 is scored 1 point. Correct completion of each of tasks 16–19 is assessed with a maximum of 2 points. Tasks 16 and 17 are considered completed correctly if two answer options are correctly selected in each of them. For an incomplete answer - one of two answers is correctly named or three answers are named, two of which are correct - 1 point is given. The remaining answer options are considered incorrect and are scored 0 points. Tasks 18 and 19 are considered completed correctly if three correspondences are correctly established. An answer in which two out of three matches are established is considered partially correct; it is worth 1 point. The remaining options are considered an incorrect answer and are scored 0 points.
The tasks of Part 2 (20–23) are checked by a subject commission. Maximum score for a correctly completed task: for tasks 20 and 21 - 3 points each; in model 1 for task 22 – 5 points; in model 2, for task 22 - 4 points, for task 23 - 5 points.
To complete the examination work in accordance with model 1, 120 minutes are allotted; according to model 2 – 140 minutes
The 2019 state final certification in chemistry for 9th grade graduates of general education institutions is carried out to assess the level of general education training of graduates in this discipline. The tasks test knowledge of the following sections of chemistry:
- The structure of the atom.
- Periodic Law and Periodic Table 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 (average).
- 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 (average).
- Pure substances and mixtures. Rules for safe work in a 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 solution environment 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.

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 exam structure, among these tasks, answer options are offered only in 15. However, for the convenience of passing tests, the site administration decided to offer answer options in all tasks. But for tasks in which the compilers of real test and measurement materials (CMMs) do not provide answer options, 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.
