Question

Consider three P, Q, R salts among them P and Q salts have different cations and
also have different coloured polyatomic anion due to charge transfer phenomenon 
while P and R salts have same cation but have different anions. Salt R 
decomposes into an acidic gas and a basic gas.

Prashant Kotian · Accepted Answer

Correct answer: A. For salt 'R': (a) NH4NO3 -Δ-> N2O (Neutral) + H2O (Neutral). (b) (NH4)2CO3 -Δ-> NH3↑ (Basic) + CO2↑ (Acidic) + H2O. (c) (NH4)2S -Δ-> NH3↑ (Basic) + H2S↑ (Acidic). (d) NH4Cl -Δ-> NH3↑ (Basic) + HCl↑ (Acidic).
