Which one is stronger:

an acid A A with p K a = 5.2 p{ K }_{ a }=5.2 or an acid B B with p K a = 5.8 p{K}_{a}=5.8 ?

A Both are equally strong B IDK

− log ⁡ K a = p K a -\log{K_a}=pK_a ; K a = 1 0 − p K a K_a=10^{-pK_a} ; K a , a c i d A < K a , a c i d B K_{a,acid A}<K_{a,acid B} ; So, acid A is stronger.
