Question

What is the approximate hydronium ion concentration and hydroxide ion concentration in bleach? Which is higher?

Answer 1

Answer 2

Bleach is basic so it has a higher hydroxide ion concentration.

Answer 3

The pH of bleach is roughly 12; recall that the pH and pOH must sum to 14, so we find pOH = 14 - 12 = 2. To determine concentration, recall:$$pOH=-\log[OH^-]\\ [OH]^-=10^{-pOH}=10^{-2}=1/100$$
