Front

What is a solution?

Back

A solution is a homogeneous mixture formed when one substance (the solute) dissolves in another substance (the solvent).

Front

What must occur for a solution to form?

Back

One substance must dissolve in another.

Front

Back

A buffer solution is a solution that resists large changes in pH when small amounts of acid or base are added.

Front

Front

What is the role of a solvent in a solution?
