A white precipitate was formed when BaCl $_{2(aq)}$ was added to an aqueous solution
of a salt X. The precipitate dissolved in dilute HCl with rapid effervescence. Salt X is likely to contain

SO $_{4}$ $^{2-}$ ions

SO $_{3}$ $^{2-}$ ions

NO $_{3}$ - ions

SO $_{3}$ $^{2-}$ - ions

Correct answer is D

Effervescence is the formation of gas bubbles in a liquid by a chemical reaction. An example of effervescence is the release of carbon dioxide which bubbles as a gas from the liquid when limestone chips, which are composed of calcium carbonate, are added to dilute hydrochloric acid.
