$Si$ and $Ge$ used for semiconductors are required to be of high purity and hence purified by:

In the $Hoop$ process for the refining of $Al$,the molten materials form three different layers and remain separated during electrolysis because ..........

Which of the following employ$(s)$ thermal decomposition of volatile iodide compounds?

Mond's process is used for the purification of:

Which process of purification is represented by the following equation?
$Ti_{\text{(Impure)}} + 2I_2$ $\xrightarrow{250^{\circ}C} TiI_4$ $\xrightarrow{1400^{\circ}C} Ti_{\text{(Pure)}} + 2I_2$
