Question

What is the secondary valence of following compounds PtCl 2 ⋅ 2 NH 3, CoCl 3 ⋅ 4 NH 3 and NiCl 2 ⋅ 6 H 2 O if moles of AgCl precipitated per mole of the given compounds with excess AgNO 3 respectively are: 0,1 and 2 (A) 6,4,4 (B) 4,6,6 (C) 4,4,6 (D) 2,4,6

PtCl 2 ⋅ 2 NH 3=[ Pt ( NH 3)2 Cl 2] CoCl 3 ⋅ 4 NH 3=[ Co ( NH 3)4 Cl 2] Cl NiCl 2 ⋅ 6 H 2 O =[ Ni ( H 2 O )6 Cl 2.

Q. What is the secondary valence of following compounds $PtC l_{2} \cdot 2 N H_{3}, C o C l_{3} \cdot 4 N H_{3}$ and $N i C l_{2} \cdot 6 H_{2} O$ if moles of $A g Cl$ precipitated per mole of the given compounds with excess $A g N O_{3}$ respectively are: $0, 1$ and $2$

$6, 4, 4$

$4, 6, 6$

$4, 4, 6$

$2, 4, 6$

$PtC l_{2} \cdot 2 N H_{3} = [Pt (N H_{3})_{2} C l_{2}]$
$C o C l_{3} \cdot 4 N H_{3} = [C o (N H_{3})_{4} C l_{2}] Cl$
$N i C l_{2} \cdot 6 H_{2} O = [N i (H_{2} O)_{6} C l_{2}$
