Question

Find the number of proton donor acid(s) from the following:

$B(OH{)}_3,Mg(OH{)}_2,Si(OH{)}_4,S{O}_2(OH{)}_2,Ba(OH{)}_2$

Answer 1

The number of proton donor acids is 3.

$B(OH{)}_3$ is boric acid and $S{O}_2(OH{)}_2$ is sulphuric acid. They both are proton donor acids. $Si(OH{)}_4$ is also a proton donor.

$Si(OH{)}_4+H_{2}O\to SiO(OH{)}_3+H_3{O}^{+}$

Magnesium hydroxide and Barium hydroxide are bases.
