Solubility and Precipitation reactions

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a homogeneous solution.

Front

What is a precipitation reaction?

Back

A precipitation reaction occurs when two soluble salts react in solution to form an insoluble salt, known as a precipitate.

What is the solubility rule for hydroxides?

Back

Most hydroxides are insoluble, except for those of alkali metals and some alkaline earth metals like Ba(OH)2 and Ca(OH)2.
