Mond's Process

Q.

If a liquid compound decomposes at its boiling point, which method $\left(s\right)$ can you choose for its purification. It is known that the compound is stable at low pressure, steam volatile and insoluble in water.

Q. Mond process is used for refining:

1. $Ni$
2. $Ag$
3. $Al$
4. $Sn$

Q.

Mond’s Process involves

1. $C{r}_2{O}_3$ $+Al$ $\stackrel{\Delta }{\to }$ $2Cr+A{l}_2{O}_3$

2. $TiC{l}_4$ $+2Mg$ $\stackrel{\Delta }{\to }$ $Ti$ $+2MgC{l}_2$

3. $Ni(CO{)}_4$ $\stackrel{\Delta }{\to }$ $Ni+4CO$

4. $Zr{I}_4$ $\stackrel{\Delta }{\to }$ $Zr+2I_2$
