Study Guide for Unit 7 and 8 Test (Fall 24)

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more dissolved solute than it can theoretically hold at a given temperature, often achieved by heating the solution and then cooling it.

Front

What type of reaction occurs when an acid and a base are mixed?

Back

A neutralization reaction occurs when an acid and a base react to form water and a salt.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one reactant breaks down into two or more products.

Front

What is the role of an indicator in acid-base titration?

Back

An indicator shows when the reaction has reached or passed the equivalence point by changing color.

Front

What does pH measure?

Back

pH measures the concentration of hydrogen ions (H+) in a solution.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.

Front

What is a saturated solution?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

Front

What is the balanced equation for the decomposition of potassium permanganate (KMnO4)?

Back

2 KMnO4 → K2MnO4 + MnO2 + O2.

Front

What is the significance of the equivalence point in titration?

Back

The equivalence point is the point at which the amount of acid equals the amount of base in a titration, indicating that the reaction is complete.
