Question

Give the correct order of $T$ or $F$ for the following statements. Use $T$ if statement is true and $F$ if it is false.
(I) In Goldschmidt thermite process aluminium acts as a reducing agent.
(II) $Mg$ is extracted by electrolysis of aq. solution of $MgC{l}_2$.
(III) Extraction of $Pb$ is possible by carbon reduction method.
(IV) Red Bauxite is purified by Serpect's Process.

• A. $TTTF$
• B. $TFFT$
• C. $FTTT$
• D. $TFTF$

Answer 1

The correct option is D $TFTF$

(A) In Gold schmidt thermite process aluminum acts as a reducing agent. $\stackrel{△}{\to }$
Thus statement is true.

(B) Mg is extracted by electrolysis of fused mixture of $MgC{l}_2$ and $NaCl$.
Thus statement is false.

(C) Extraction of Pb is possible by carbon reduction method. $PbS+\frac{3}{2}{O}_2\to PbO+S{O}_2$

The oxide is reduced to Pb.
Thus statement is true.

(D) Red Bauxite (which contains iron oxide as the main impurity) is purified by Bayer's process or Hall's process. White bauxite (which contains silica as chief impurity) is purified by serperck's process.
Thus statement is false.
