Calculate the change in pH caused by adding 10.0 mL of 3.30-M HCl to 440. mL of each of the following solutions.

Note that it is possible to get the original and final pH's correct to within the allowed tolerance but miss the change in pH because the pH change is smaller and has a smaller allowed error. If this happens, check your answers for the initial and final pH values.

- Enter all of your answers to two places past the decimal point.
- pH changes can be positive or negative.

a) water
pH before mixing =
pH after mixing=
pH change =

b) 0.11 M C2H3O21-
pH before mixing =
pH after mixing=
pH change =

c) 0.11 M HC2H3O2
pH before mixing =
pH after mixing=
pH change =

d) a buffer solution that is 0.11 M in each C2H3O21- and HC2H3O2
pH before mixing =
pH after mixing=
pH change =
