A 25.00 mL sample of 0.280 M NaOH analyte was titrated with 0.750 M HBr at 25 °C. Calculate the initial pH before any titrant was added. Calculate the pH after the 5.00ml titrant was added.

Determine the pH change when 0.069 mol KOH is added to 1.00 L of a buffer solution that is 0.326 M in HClO and 0.290 M in ClO^-.

pH after addition ? pH before addition = pH change =
