In (NH4)2SO4, [SO4] will form acidic ion on dissociation.
True
False
Acidic ions are negatively charged and [SO4] forms a negative ion SO24−.
Dilute acids like hydrochloric acid (HCl), sulphuric acid H2SO4 react with certain active metals to evolve hydrogen gas and form their metallic salts.
H+ ion comes from the ionization of bases.
Bleaching powder in reaction with dilute hydrochloric acid releases hydrogen gas(H2).
