Question

Which of these has a higher hydrogen ion concentration? *

Solution A: POH 8.9
Solution B: POH 5.5

Answer 1

pOH = 8.9

Step-by-step explanation:

pOH+pH = 14

pH= 14- pOH

pOH = 8.9, pH=14-8.9 = 5.1

pOH = 5.5, pH=14-5.5 = 8.5

Than less pH , than more H+ ion concentration.

pH=5.1 <pH=8.5

pH=5.1 is more acidic solution

pH=5.1 or pOH=8.9 has a higher H+ concentration.
