Rank the following 0.100 M solutions in order of increasing H3O+ concentration:
HF, Ka = 6.3 × 10−4; HCN, Ka = 6.2 × 10−10; HOCl, Ka = 4.0 × 10−8

HF < HCN < HOCl

HCN < HOCl < HF

HOCl < HCN < HF

HF < HOCl < HCN

HOCl < HF < HCN

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct
