Acids & Bases: Dilution

Front

What happens to the pH of an acidic solution when water is added?

Back

The pH of the solution increases.

Front

What happens to the hydrogen ion concentration when an acidic solution is diluted with water?

Back

The hydrogen ion concentration will decrease.

Front

What is an acid?

Back

A substance that donates hydrogen ions (H+) in a solution.

Front

What is a base?

Back

A substance that accepts hydrogen ions (H+) or donates hydroxide ions (OH-) in a solution.

Front

What is pH?

Back

A measure of how acidic or basic a solution is, on a scale of 0 to 14.

Front

What happens to the pH of a base when it is diluted with water?

Back

The pH of the solution decreases.

Front

What is the effect of dilution on the concentration of hydroxide ions in a base?

Back

The concentration of hydroxide ions decreases.

Front

What is the relationship between hydrogen ion concentration and pH?

Back

As hydrogen ion concentration increases, pH decreases.

Front

What is the neutral pH value?

Back

7, which is neither acidic nor basic.

Front

What is a neutral solution?

Back

A solution with a pH of 7, where the concentration of H+ and OH- ions are equal.
