Complete the table below:
What is the pH of the solution created by combining 0.70 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)? with 8.00 mL of the 0.10 M HC2H3O2(aq)?
mL NaOH: 0.70
pH w/ HCl: 1.08
pH wHC2H3O2: 3.23

Complete the table below:
What are the pH values if you take into account that the 8.00 mL of 0.10 M Acid was first diluted with 100 mL of water (like it will be in the experiment you perform in lab)?
mL NaOH: 0.70
pH w/ HCl: 2.14
pH w/ HC2H3O2: ???

I got everything except for the 2nd pH w/ HC2H3O2. Please help!!
