The `[H^(+)]` ion concentration present in `"0.01 mol dm"^(-3)` acetic acid solution is_____ `10^(-4) mol dm^3`. (Given: `sqrt(K_a) = 4.17 xx 10^(-3)` ).

Text Solution

Verified by Experts

The correct Answer is:
4.17
Concentration of `CH_3 COOH = 0.01 "moldm"^(-3)`
`[H^(+)]=sqrt(K_a.C)= 4.17 xx10^(-3)xxsqrt(0.01)`
`= 4.17 xx10^(-4) "mol dm"^(-3)`
