Question

sodium is extracted from rock salt.

a)electrolysis is needed for this.explain why?
b)write a word equation for this?
c)say which ions are oxidized and reduced?

plz give my answer as fast possible!​

Answer 1

Answer:

a) Sodium is extracted by electrolytic reduction of molten sodium chloride. On passing electricity through molten sodium chloride, decomposition occurs and sodium metal and chlorine gas are formed. ... The cathode produces electrons to reduce sodium ions to sodium atoms (or sodium metal) by acting as reducing agent.

b) 2na+cl2

c) Oxidation numbers represent the potential charge of an atom in its ionic state. If an atom's oxidation number decreases in a reaction, it is reduced. If an atom's oxidation number increases, it is oxidized.

Answer 2

Answer:

Here's your answer!!!

Explanation:

Sodium is highly reactive metal which is present in the form of oxides or chlorides.

The process of electrolysis is carried out for the extraction of highly reactive metal.

The word equation is

Sodium chloride ------>Sodium+Chlorine

The reaction is NaCl---->Na+Cl

At anode

Cl^(-)-------->Cl +e (oxidation)

At cathode

Na^(+) +e------->Na(metal)(reduction)
