When excess of silver nitrate solution is added to aqueous solution containing 0.1 molar `CoCl_(3).xNH_(3)`. If 43.05 g of silver chloride precipitated, then x value is

Text Solution

Verified by Experts

`n_(AgCl) = (43.05)/(143.5) = 0.3, 0.1` mole of `CoCl_(3).xNH_(3)`gives 0.3 mole of AgCl. 1 mole of `CoCl_(3).XNH_(3)` gives 3 mole of AgCl. Secondary Valency of `Co^(+3)` is 6 and Primary Valency is 3.
