Vedclass · Answer

(C) The acidic strength depends on the dissociation constant $(K_a)$ of the acids. $H_2SO_4$ is a strong mineral acid with a very high $K_a$ value. $CH_3COOH$ is a weak organic acid with $K_a \approx 1.8 imes 10^{-5}$. $H_2CO_3$ is a weaker acid than acetic acid with $K_a \approx 4.3 imes 10^{-7}$. Therefore,the decreasing order of acidic strength is $H_2SO_4 > CH_3COOH > H_2CO_3$. Thus,the increasing order is $H_2CO_3 < CH_3COOH < H_2SO_4$.
