2nd practice for Solutions, Acids and Bases

Front

What is a neutralization reaction?

Back

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

Front

What is formed when an acid reacts with a base?

Back

Salt and water are formed when an acid reacts with a base.

Front

What is the pH of a neutral solution?

Back

A neutral solution has a pH of 7, but not all neutralization reactions result in a pH of exactly 7 due to the presence of other substances.

Front

Which solution is least likely to conduct electricity?

Back

A sugar solution is least likely to conduct electricity because it does not dissociate into ions.

Front

What is an unsaturated solution?

Back

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

Front

What happens in a saturated solution?

Back

In a saturated solution, no more solute can dissolve at a given temperature; it has reached its maximum concentration.

Front

What is a concentrated solution?

Back

A concentrated solution contains a large amount of solute relative to the amount of solvent.

Front

How can you dilute a concentrated solution?

Back

You can dilute a concentrated solution by adding more solvent, such as water.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What effect does temperature have on the solubility of most salts?

Back

For most salts, solubility increases as temperature increases.
