Question

Which of the following is best suited to dry crystals of ammine salts ?(complexes in which $N{H}_3$ is a ligand and $\left[Ni{\left(N{H}_3\right)}_6\right]B{r}_2$ )

• A. Anhydrous $CaC{l}_2$
• B. Anhydrous $CaO$
• C. A mixture of $CaO$ and $N{H}_{4}Cl$
• D. None

Answer 1

Answer: (C)

A mixture of $CaO$ and $N{H}_{4}Cl$

The crystals of ammine salts are dried by using a mixture of calcium oxide($CaO$) and ammonium chloride($N{H}_{4}Cl$).
