pH and pOH

pH and pOH. Measuring acidity and basicity. pH. The pH scale is used to measure the acidity of a solution. pH is a measure of the concentration of hydronium ions, [H 3 O + ], in a solution. The scale ranges from 0 - 14 A pH value of 7 indicates neutrality.

Acids and Bases

Acids and Bases. Dissociation. In water all ionic compounds dissociate into its ionic parts So NaCl in water dissociates into Na + and Cl - So H 3 PO 4 dissociates into 3H + and PO 4 -3 Remembers ionic compounds are formed by metals and nonmetals or by metals and polyatomic ions.
