7th Edition Problem 6B.9 Solution

Postby Venya Vaddi 1L » Thu Jan 17, 2019 8:25 pm

Is there an error in the 7th edition solution manual for 6B.9? For (i), when I calculate -log[H3O+], I got -0.176, not +0.176 like the solution manual says. Can someone explain how to get the correct answer?

I got the same thing. I think that it's an error in the solutions manual. A 1.0M solution of a strong acid will have a pH of 0, so we would expect a >1.0M solution of a strong acid to have a negative pH.
