Solutions, Acids and Bases Studyguide and Review

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (the solute) is dissolved in another (the solvent).

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

What is the characteristic ion of an acid?

Back

Hydrogen ion (H⁺).

Front

What do acids produce when dissolved in water?

Back

Hydrogen ions (H⁺).

Front

What is a base?

Back

A substance that produces hydroxide ions (OH⁻) in water.

Front

What do bases produce when dissolved in water?

Back

Hydroxide ions (OH⁻).

Front

What is a neutral solution?

Back

A solution with a pH of 7, where the concentration of hydrogen ions equals the concentration of hydroxide ions.

Front

What is pH?

Back

A measure of the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic).

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.

Front

What is the role of water in acid-base reactions?

Back

Water acts as a solvent and can also participate in the reaction by donating or accepting protons (H⁺).
