1 11 ml of 00100 m hcl are added to 250 ml of a buffer, Ask an Expert

Academics

1. 11 mL of 0.0100 M HCl are added to 25.0 mL of a buffer solution that is 0.010 M HC2H3O2 and 0.11 M C2H3O2-. What is the pH of the resulting solution?

2. Calculate the pH of a 0.10 M NaHX salt solution. Ka (H2X) = 2.1 x 10-2 Ka (HX-) = 8.2 x 10-8
3. Calculate the pH of a 0.10 M NaHX salt solution. Ka (H2X) = 9 x 10-5 Ka (HX-) = 5.3 x 10-11
