Question
Consider the weak acids below and their corresponding Ka values. Rank the acids from weakest to strongest.
HNO2 (Ka = 4.0 x 10-4)
HIO (Ka = 2.0 x 10-11)
C6H5COOH (Ka = 6.5 x 105)
O (weakest) HNO2 < C6H5COOH < HIO (strongest)
O (weakest) C6H5COOH < HIO < HNO2 (strongest)
(weakest) HIO < HNO2 < C6H5COOH (strongest)
O All weak acids are equally weak
O (weakest) HIO < C6H5COOH < HNO2 (strongest)
