Sample chemistry test questions vary depending on the topics the test covers and other factors, such as the grade level and format of the test. An example of an SAT-type chemistry question is, "What type of reaction occurs between silver and chloride ions in water solution?" The answer is precipitation.
Silver chloride, or AgCl, forms when silver cations and chloride anions react. Because silver chloride is not soluble in water, it precipitates out of the solution.
A sample organic chemistry test question is, "Why is carbon able to form such a wide range of compounds?" The answer is that carbon is able to form four covalent bonds with many types of atoms, and its ability to bond covalently with other carbon atoms is virtually limitless. This chemical nature of elemental carbon makes a vast range of carbon-based structures possible.
A multiple-choice chemistry exam that covers the topic of acids and bases may feature a question such as, "Which of the following is a potential pH value for an acidic solution?" Any pH value below seven indicates an acidic solution. Conversely, if a question asks which pH value is possible for a basic solution, the correct answer is any value above seven.
