A silverly white metal, lighter than water can be produced only by the electrolysis of its fused chloride, with great difficulty. It is the sixth most abundant metal of earth crust. The metal is used in Wurtz reaction, Wurtz-Fitting reaction and Birch reduction. The metal is

A

K

B

Mg

C

Na

D

Ca.

Text Solution

Verified by Experts

The correct Answer is:
C
Na, a silvery white metal, is obtained with great difficulty by the electrolysis of fused NaCl. It is also the sixth most abundant element in the earth's crust, whereas K is the seventh most abundant element in earth's crust.

Read the given statements carefully and state (T) for true and (F) for false ones. I. Metals of low reactivity can be extracted directly by the electrolysis of their molten ores. II. Prior to reduction, metal sulphides and carbonates must be converted to metal oxides. III. Metals of high reactivity can be extracted by electrolytic oxidation. IV. Thermite reaction is a displacement reaction and is highly exothermic.

Alkali and alkaline earth metals have low ionisation enthalpies and hence exhibit characteristic flame colouration. They have high negative electrode potentials and hence are strong reducing agents. They dissolve in liquid ammonia to give a solution which conducts electricity and act as strong reducing agent. being stronger reducing agent than hydrogen, they are usually prepared by the electrolysis of their fused chlorides. Their oxides are basic and the basic strength increases down the group. The solubility of carbonates and sulphates of alkali and alkaline earth metals show opposite trends. only the carbonates of Li and alkaline earth metals decompose on heating. The bicarbonates of both alkali and alkaline earth metals on heating give carbonates. The compound insoluble in acetic acid is
