what is the pH of a solution that results from adding 0.043 mol Sr(OH)2 (s) to 1.31 L of a buffer comprised of 0.27 M benzoic acid, C6H5COOH and 0.27 M sodium benzoate, C6H5COONa?
If 60mL of 0.1M CH3COOH is titrated with 0.2M NaOh, what will the pH be when: 1. Initial, before adding NaOH 2. 15mL of NaOH is added 3. 30mL of NaOH is added I worked the pH levels to 2.87, 4.74, and 10.21 (none, 15mL, 30mL NaOH).
