What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is pH?

Back

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

Front

What is a saturated solution?

Back

A saturated solution is a solution in which no more solute can dissolve at a given temperature.

Front
