Calculate the change in pH caused by adding 10. mL of 2.7-M HCl is added to 400. mL of each of the following s?

i have to do this for homework due in a week, and ive been trying to do it for 4 days, i just dont understand it. can someone please explain how to do this problem? please



Calculate the change in pH caused by adding 10. mL of 2.7-M HCl is added to 400. mL of each of the following solutions.



a) water



pH before mixing =

pH after mixing= .

pH change =



b) 0.13 M CH3COO1- Acid-base table



pH before mixing =

pH after mixing=

pH change =



c) 0.13 M CH3COOH



pH before mixing =

pH after mixing=

pH change =



d) a buffer solution that is 0.13 M in each CH3COO1- and CH3COOH



pH before mixing =

pH after mixing=
