Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 3.35-M HCl to 550. mL of each of the following solutions.
Change is defined as final minus initial, so if the pH drops upon mixing the change is negative.
a) water
| pH before mixing = | |
| pH after mixing= | |
| pH change = |
b) 0.134 M C2H3O21-
| pH before mixing = | |
| pH after mixing= | |
| pH change = |
c) 0.134 M HC2H3O2
| pH before mixing = | |
| pH after mixing= | |
| pH change = |
d) a buffer solution that is 0.134 M in each C2H3O21- and HC2H3O2
| pH before mixing = | |
| pH after mixing= | |
| pH change = |

Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 2.05-M HCl to 570. mL of each of the following solutions.
a) water
before mixing = 7
After mixing = 1.45
b) 0.135 M C2H3O21-
Before mixing = 8.95
After mixing = ?
c) 0.135 M HC2H3O2
Before mixing = ?
After mixing = ?
d) a buffer solution that is 0.135 M in each C2H3O21- and HC2H3O2
Before mixing = ?
After mixing = ?
I've tried this so many times and I don't understand it. Is there a formula or a set of formulas for this ?? Can someone please just spell it out for me step by step and why. Please and thank you!
