Nickel (II) ion forms a complex K x[ Ni ( CN )4]. The value of ' x ' is. (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Charge on complex ion =+2+4 ×(-1)=-2 ∴ Two K +ions are required to balance the charge on the complex ion. ∴ Formula of complex is K 2[ Ni ( CN )4]. ∴ The value of ' x ' is 2 .

Q. Nickel $(II)$ ion forms a complex $K_{x} [N i (CN)_{4}]$ . The value of ' $x$ ' is______.

Charge on complex ion $= + 2 + 4 \times (- 1) = - 2$
$∴$ Two $K^{+}$ ions are required to balance the charge on the complex ion.
$∴$ Formula of complex is $K_{2} [N i (CN)_{4}]$ .
$∴$ The value of ' $x$ ' is $2$ .

Q. Nickel (II) ion forms a complex Kx​[Ni(CN)4​]. The value of ' x ' is______.

Charge on complex ion =+2+4×(−1)=−2 ∴ Two K+ions are required to balance the charge on the complex ion. ∴ Formula of complex is K2​[Ni(CN)4​]. ∴ The value of ' x ' is 2 .
