For the reaction given below: CoCl 3 . xNH 3 + AgNO 3 aq → If two equivalents of AgCl precipitate out, then the value of x will be _______

Correct answer

0

Step-by-step solution

CoCl 3 . xNH 3 + AgNO 3 → AgCl ↓ 2   mol For 2 moles of AgCl precipitate out,only two chloride ions should be present out side the coordination sphere that is in the ionization sphere. Hence, the formula of the complex should be Co NH 3 5 Cl Cl 2 Co NH 3 5 Cl Cl 2 + AgNO 3 → AgCl ↓ 2   mol So, the value of x should be 5. x = 5 .
