What type of ion does a base produce when dissolved in water?

Back

Hydroxide ion (OH-) is produced by bases when dissolved in water.

Front

When dissolved in water, what do bases produce?

Back

Bases produce hydroxide ions (OH-) when dissolved in water.

What is the pH of ammonia, and what does it indicate about its nature?

Back

Ammonia has a pH of 12, indicating that it is a base.

Front

Which solution has the greatest solubility as temperature increases: KNO3, NH4Cl, KCl, or NaCl?

Back

KNO3 has the greatest solubility as temperature increases.

Front

What does it mean if a solution is described as unsaturated?

Back

An unsaturated solution contains less solute than it can dissolve at a given temperature.

Front

Define a saturated solution.

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is the difference between acids and bases in terms of pH?

Back

Acids have a pH less than 7, while bases have a pH greater than 7.

Front

What is the role of hydroxide ions in a basic solution?

Back

Hydroxide ions (OH-) increase the pH of a solution, making it basic.

Front

What is the general formula for calculating pH?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH of the solution decreases when an acid is added.
