What is the pH of the solution created by combining 12.30 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)?

Question

What is the pH of the solution created by combining 12.30 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:12.30
pH w/ HCl _________
pH w/ HC2H3O2 _________

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?

mL NaOH:12.30
pH w/ HCl _________
pH w/ HC2H3O2 _________

Answer 1

I have worked this problem twice in the last couple of days for others. I'll look up the last one and post it here.

Answer 3

Thank you so much!!!

Answer 4

wait but i keep negative values for the moles of HCl because I have a large volume of NaOH unlike the other problems...
