What is pH?

Back

pH is a measure of how acidic or basic a solution is, on a scale from 0 to 14.

Front

What is a basic substance?

Back

A basic substance has a pH greater than 7 and can accept protons or donate electron pairs.

Front

What is the relationship between temperature and solubility?

Back

Generally, as temperature increases, the solubility of most solids in liquids also increases.

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows the relationship between the solubility of a substance and temperature.
