Reference no: EM13175391

Phenolphthalein. The pH at the equivalence point is greater than 7.0. A 25.0 mL sample of 0.0200 M NH3(aq) is titrated with 0.0100 M HCl(aq). What is the pH at the equivalence point? (Kb of NH3 = 1.8 A 20.0 mL sample of 0.20 M sodium acetate is titrated with 0.11 M HCl(aq). What is the pH after the addition of 50.0 mL HCl(aq)?
