Acids, Bases, & Solutions

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is a solution?

Back

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

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution.

Front

What is a solvent?

Back

A solvent is the substance that dissolves the solute in a solution.

Front

What does pH measure?

Back

pH measures the acidity or basicity of a solution on a scale from 0 to 14.

Front

What is a saturated solution?

Back

A saturated solution is a solution that has dissolved the maximum amount of solute at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution is a solution that contains more dissolved solute than what is normally possible at a given temperature.

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases, while the solubility of gases decreases.

Front

What is the pH range for neutral solutions?

Back

The pH range for neutral solutions is 7.
