PS Acids, Bases, and Solutions Test Review

Front

What is a saturated solution?

Back

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

Front

What is the difference between a solute and a solvent?

Back

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

Front

What does pH measure?

Back

pH measures the acidity or basicity of a solution, indicating the concentration of hydrogen ions (H+) present.

Front

What is a supersaturated solution?

Back

A supersaturated solution is a solution that contains more solute than it can normally hold at a given temperature.

Front

What is the role of hydroxide ions (OH-) in a solution?

Back

Hydroxide ions (OH-) indicate the basicity of a solution; higher concentrations of OH- result in a higher pH.

Front

What is a colloid?

Back

A colloid is a mixture where tiny particles of one substance are evenly distributed throughout another substance, but do not settle out.

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture in which solid particles are dispersed in a liquid but can settle out over time.

Front

How can you increase the solubility of a solute in a solvent?

Back

You can increase solubility by raising the temperature, stirring the solution, or increasing the surface area of the solute.

Front

What is the significance of the solubility curve?

Back

The solubility curve shows the relationship between temperature and the solubility of a substance, indicating how much solute can dissolve at different temperatures.

Front

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

Back

When an acid is added to a solution, the pH decreases, indicating an increase in hydrogen ion concentration.
