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.
