Identify the number of replaceable hydrogen ions (H+) in the following acids:
(i) HCl (if) CH3COOH
(hi) H2SO4 (iv) H3PO4,
Replaceable H+ ions.

(i) HCl — One replaceable H+ion
(ii) CH3COOH - One replaceable H + ion
(iii) H2SO4 - Two replaceable H + ion
(iv) H3PO4 - Three replaceableH + ions

Why only one replaceable ion in CH3COOH?
