Question

What is the pH of a 0.01 M benzoic acid solution?

Answer 1

pH = - log[H\(^+\)]

The units for [H\(^+\)] are in M which is mol/L

Answer 2

the Ka for benzoic acid is \(6.3*10^{-5}\). Use an ICE table approach

Answer 3

ICE tables are so confusing.
Just set up the K\(\sf _a\) equation.

Answer 4

@abb0t sometimes true, but the KA equation is just the end result of the ICE table

Answer 5

Benzoic acid is a weak acid. I have used a weak acid pH calculator. The answer is found to be pH = 3.12
