Question
Rank the equal molar solutions of the following acids from the highest to the lowest Ka.
HBr > H3As > H₂Se
H₂Se > H3As > HBr
H3As > HBr > H₂Se
H3As> H₂Se > HBr
HBr > H₂Se > H3As
H₂Se > HBr > H3As

Expert Solution
Step 1: Relation between value of Ka and acidic strength

Answer:

Higher the value of dissociation constant Ka, stronger will be the acid and vice versa, therefore in order to find the relative value of Ka, we have to find out the relative order of acidic strength of the given compounds.
