SYNTHESIS

Explain the meaning of the symbols as they are used in this expression. + means that the substances chemically combined.

are not

A substance which will resist changes in pH within reasonable limits

buffer

Accelerates a chemical reaction without being used up in the reaction

catalyst

When a reversible reaction is occurring in both directions at the same rate
