1.2 x 10 ºg

Correct option is

Let the solubility of AgBr be S mol litre

AgBr Ag+Br¯

Hence, [Ag][Br] = 5 x 10-13

[Ag+] = 0.05

So [Br] 10-¹¹M.

It means 10-11 moles of KBr moles in 1 litre of solution.

molecular mass of KBr = 120 gmol -1

So 1.2 x 10 g of KBr to be added to 1 litre of 0.05M solution of silver nitrate to start precipitation of AgBr.
