Acids and Bases

Front

What is the definition of 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 the definition of 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 pH?

Back

pH is a measure of the acidity or basicity of a solution, on a scale from 0 to 14.

Front

What is molarity?

Back

Molarity is a measure of concentration, defined as the number of moles of solute per liter of solution (mol/L).

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

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 supersaturated solution?

Back

A supersaturated solution contains more dissolved solute than a saturated solution at the same temperature.

Front

What is the pH range for acids?

Back

The pH range for acids is from 0 to less than 7.

Front

What is the pH range for bases?

Back

The pH range for bases is from greater than 7 to 14.
