7th Edition 6B.9

Postby Kathryn Wilhem 1I » Wed Jan 16, 2019 8:51 pm

For parts (i) and (ii) of the problem, we are given the [H30+] = 1.50M and [OH-] = 1.50M respectively. When I calculated the pH and pOH, I found that the answer was -0.176. When we know that taking the log of the concentration will give us a positive answer, do we just not put a negative sign in front of it?

pH =-log[H3O+], if you plug in the 1.5, you should get about 0.176
