A. $$\mathrm{Zn}^{2+}, \mathrm{Ti}^{2+}$$
B. $$\mathrm{Cr}^{2+}, \mathrm{Fe}^{2+}$$
C. $$\mathrm{Ti}^{3+}, \mathrm{Cu}^{2+}$$
D. $$\mathrm{V}^{2+}, \mathrm{Cu}^{+}$$
Choose the correct answer from the options given below :
At a given temperature and pressure, the equilibrium constant values for the equilibria are given below:
$$\begin{aligned} & 3 \mathrm{~A}_2+\mathrm{B}_2 \rightleftharpoons 2 \mathrm{~A}_3 \mathrm{~B}, \mathrm{~K}_1 \\ & \mathrm{~A}_3 \mathrm{~B} \rightleftharpoons \frac{3}{2} \mathrm{~A}_2+\frac{1}{2} \mathrm{~B}_2, \mathrm{~K}_2 \end{aligned}$$
The relation between $$\mathrm{K}_1$$ and $$\mathrm{K}_2$$ is :
Arrange the following compounds in increasing order of their solubilities in chloroform: $$\mathrm{NaCl}, \mathrm{CH}_3 \mathrm{OH}$$, cyclohexane, $$\mathrm{CH}_3 \mathrm{CN}$$
Identify the incorrect statement about $$\mathrm{PCl}_5$$.
