1. Calculate the pH of the solution formed when 10.0 mL of 0.200 M NaOH is added to:
A) 5.0 mL of 0.100 M of benzoic acid, C6H5COOH
B) 20.0 mL of 0.100 M of benzoic acid, C6H5COOH
C) 30.0 mL of 0.100 M of benzoic acid, C6H5COOH
a solution of benzoic acid (c6h5cooh) that is 0.20 m has a ph of 2.45. what is ka for benzoic acid?
What is the pH of a solution made up of 50.0 mL of 0.20 M of benzoic acid and 55.00 mL of 0.23 M sodium benzoate. pKa of benzoic acid is 4.20.
