In van Arkel method,if $I_2$ is introduced at $1700 \ K$ over impure metal,the product will be :

Identify the appropriate electrodes for the electrolytic refining of a copper sample containing zinc as an impurity.

Given below are two statements.
Statement $I:$ During electrolytic refining,blister copper deposits precious metals.
Statement $II:$ In the process of obtaining pure copper by electrolysis method,blister copper is used to make the anode.
In the light of the above statements,choose the most appropriate answer from the options given below.

Which process of purification is represented by the following scheme?
$\text{Ti}_{\text{impure}} + 2I_2$ $\xrightarrow{250^{\circ}C} TiI_4$ $\xrightarrow{1400^{\circ}C} \text{Ti}_{\text{pure}} + 2I_2$

$A$ low boiling point metal contains a high boiling point metal as an impurity. The correct refining method is:

Which of the following properties of pure metal makes it more useful than the corresponding alloy?
