What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (solute) is dissolved in another (solvent).

Front

What is a solute?

Back

A solute is the substance that is dissolved in a solution. For example, in a sugar-water solution, sugar is the solute.

Front

What is a solvent?

Back

A solvent is the substance in which the solute is dissolved to form a solution. Water is a common solvent.

Front

What does it mean for a solution to be saturated?

Back

A saturated solution is one that contains the maximum amount of solute that 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 solute than can normally dissolve at a given temperature, often achieved by heating the solution.

Front

How does temperature affect solubility?

Back

Generally, increasing the temperature increases the solubility of solids in liquids, while the solubility of gases decreases.

Front

What is pH?

Back

pH is a measure of how acidic or basic a solution is, on a scale from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

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

Back

Adding an acid to a solution decreases the pH, making the solution more acidic.

Front

What is the relationship between pH and acidity?

Back

The lower the pH, the stronger the acid; a higher pH indicates a weaker acid.
