at 30 degree celsius , the solubility of ag2co3 (Ksp= 8 * 10^-12) would be maximum in 1 litre of ? a) pure water b) 0.05 M NH3 c)0.05 agno3 d)0.05m na2co3 Please explain Share with your friends Share 52 Vartika Jain answered this Dear Student, (a)In pure water :Ag2CO3 ↔ 2Ag+ + CO32-(b) In NH3 :Ag2CO3 ↔ 2Ag+ + CO32- 2Ag+ +4NH3 ↔ 2Ag(NH3)2+Overall: Ag2CO3 + 4NH3↔2Ag(NH3)2+ + CO32-Here a complex formation is taking place, due to the formation of complex the reaction between silver ionsa and ammonia shifts the solubility equilibria in the forward direction, which in turns increases the solubility. (c) an (d) : Due to the presence of common ion in these reactions, the solubility is supressed. Therefore, Ag2CO3 will be most soluble in NH3. Hence, correct answer is (b) 79 View Full Answer
