Question

how is sodium obtained from molten sodium chloride give equation for the reaction​

Answer 1

• Sodium is obtained from molten sodium chloride by the process of electrolysis.

• Electricity is passed in the aqueous solution of sodium chloride where Sodium metal gets deposited in the anode and chlorine gas gets deposited at the cathode.

• This method is used to obtain the metals high in the reactivity as reducing agent cannot be used to obtain with these metals.

• This method can also be used for other metals like Potassium, Magnesium and Calcium.

• Equation for the reaction: 2NaCl(aq) -------------> 2Na(s)  + Cl2(g)
•                                                             Electricity
