Determine the pH (to two decimal places) of the solution that is produced by mixing 552 mL of 7.68×10^-3 M HCl with 60.3 mL of 1.80×10^-3 M KH.

Solutions

Expert Solution

millimoles of HCl = 552 x 7.68 x 10^-3 = 4.24

millimoles of KH = 60.3 x 1.80 x 10^-3 = 0.108

H+ + H- ----------------> H2
4.24 0.108 0

4.13 0 0.108

[H+] left = 4.13 / (552 + 60.3)

= 6.475 x 10^-3 M

pH = -log [H+]

pH = 2.17
