7th Edition Problem 6B.9 Solution

Postby Venya Vaddi 1L » Wed Dec 05, 2018 3:30 pm

Is there an error in the solutions manual for 6B.9 (7th edition)? The concentration of H30+ is given as 1.50 M in the problem, and using the information to calculate pH I got -0.176 but the solutions manual writes +0.176, which does not correlate to the hydronium ion concentration provided.

You should take the negative log of the H3O+ concentration so the answer is actually -(-.176) which is simplified to +.176
