Answer :-

46. Because on addition of C2O42- the equilibrium will shift towards the right side i.e. In the forward direction because it is reactant according to Le Chatelier principle to minimize its effect.

47. Because on dissociation Ag2CO3 will give two Ag+ and 1 CO32- ions.

Ag2CO3(s) <====> 2Ag+(aq) + CO32-(aq)
