Question

Hello, im having major issues with this problem...A 100.0-mL solution of 0.017 M CH3COOH (Ka = 1.8 10-5) is titrated with 0.025 M NaOH.

Now, I've gotten some the answers all ready (right answers have *)....but three of them are wrong, can someone tell me what to do?
1.) initial pH - this is 3.25 *



2.) after addition of 10.0 mL of NaOH- 5.51


3.) after addition of 34.0 mL of NaOH- 4.75*


4.) after addition of 68.0 mL of NaOH-3.29

5.) after addition of 100.0 mL of NaOH-2.32

Answer 1

I'm suppose to be finding out the pH of each solution...sry
