Solutions, Acids and Bases Studyguide and Review

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, leading to excess solute that can crystallize out.

Front

How can you create a saturated solution of NaNO3 at 10°C?

Back

Add approximately 18 grams of NaNO3 to the solution.

Front

What is the pH range for acidic solutions?

Back

The pH range for acidic solutions is from 0 to 6.

Front

Which substance is the best base for neutralizing battery acid?

Front

What does a pH value of 2 indicate?

Back

A pH value of 2 indicates a strong acid.

Front

What happens to the solubility of KNO3 as temperature increases?

Back

The solubility of KNO3 increases as temperature increases.

Front

Define a saturated solution.

Back

A saturated solution is one in which the maximum amount of solute has been dissolved at a given temperature.

Front

What is the difference between unsaturated and supersaturated solutions?

Back

An unsaturated solution can still dissolve more solute, while a supersaturated solution contains more solute than can normally dissolve.

Front

What is the pH of a neutral solution?

Back

The pH of a neutral solution is 7.

Front

What is the effect of temperature on the solubility of most solids?

Back

For most solids, solubility increases as temperature increases.
