QUESTION
Rank the following aqueous solutions in order of increasing pH (lowest to highest):10 M NaNO3 II:10 M NaHSO3 III:
(5) II < I < III
Answer is 5
I was given Ka's but I don't know if it's necessary to use them.
Given:
Carbonic acid, H2CO3, Ka1 = 4.5x10−7, Ka2 = 4.7x10−11
Sulfurous acid, H2SO3, Ka1 = 1.4x10−2, Ka2 = 6.5x10−8
