Question

What is the pH of the solution created by combining 2.70 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)?

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)?

they ask you to find the pH for both the HCl and the HC2H3O2.

i understand the first question its just the second question that is confusing me

Answer 1

i keep trying to do it and i don't understand what i am doing wrong

Answer 2

If you would like to post your work, I'm sure I can find the error. Since this is a multipart question. you may feel better about doing it piece-meal although that will take longer because it takes time for you to post and me to read, repost etc etc.

Answer 3

Answer 4
