[H,O*], [OH], and pH Important equations: [H,O") x [OH'] = 1.00 x 1014 pH = -log[H,O"] A solution has a pH = 11.75 .Determine whether this solution is acidic, basic, or neutral. Calculate the [H,O") and [OH'] for this solution 2 Write the net ionic equation of NaHSo, with water that explains why a solution of NaHSO, is acidic. Write the net ionic equation of NaHCo, with water that explains why a solution of NaHCO, is basic.
