Back

What happens to the solubility of most solids in water as temperature increases?

Back

The solubility of most solids in water increases as the temperature increases.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (solute) is dissolved in another (solvent).

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture in which particles can be seen and easily separated by settling or filtration.

Front

What is an acid?

Back

An acid is a substance that donates hydrogen ions (H+) in a solution and typically has a sour taste.

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H+) or donates hydroxide ions (OH-) in a solution and typically has a bitter taste.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Back

Blue litmus paper turns red in the presence of an acid.

Front

What color does red litmus paper turn in the presence of a base?

Back

Red litmus paper turns blue in the presence of a base.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.
