Calculating Concentrations with Units and Dilutions

Normality is the only concentration unit that is reaction dependent. Example: 1 M sulfuric acid (H 2 SO 4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles of H + ions. On the other hand, 1 M sulfuric acid is 1 N for sulfate precipitation, since 1 mole of sulfuric acid provides 1 mole of sulfate ions.
