Textbook question 6B.9

Postby Paige Lee 1A » Sat Nov 30, 2019 1:05 pm

Why is the pH of acid #1 0.176? Why isn't it -0.176?
Isn't the formula for pH: -log[H3O+] ? So why isn't the pH negative after you plug in 1.50mols/L for the [H3O+]?

I think this might be an error in the solutions manual. I got the same numbers and answer that you did.

I saw this too, is there somewhere we can double check for the answers? Also, [OH]x[pOH]=10^-14. If you use the numbers in the answer key it doesnt work, but if you use the numbers we got, it does? So I'm thinking it probably was an error.
