Question

Give the properties and preparation process with chemical equations of:

(i) sodium carbonate (washing soda)

(ii) sodium chloride (common salt)

(iii) sodium hydroxide (caustic soda)

(iv) sodium hydrogencarbonate (baking soda)

Answer 1

Answer:

Hi Buddy ❤

Here Is Ur Answer

Chemical Formula of Following Compounds are :-

(1) Sodium(Na) Carbonate(CO3) = (Na2CO3.10H2O)

(2) Sodium(Na) Chloride(Cl) = NaCl

(3) Sodium(Na) Hydroxide(OH) = NaCl

(4) Sodium(Na) HydrogenCarbonate(HCO3) = NaHCO3

Explanation:

(1) Sodium Carbonate AKA Washing Soda

PROPERTIES :-

• It is a crystalline solid which is white in colour.

• Sodium carbonate is basic in nature.

• It has a melting point of 851°C

PREPARATION:- When the reaction of baking soda NaHCO₃ takes place in the presence of heat baking soda NaHCO₃ is heated, sodium carbonate, water and CO₂ are produced. Sodium carbonate obtained is dissolved in water and recrystallization of sodium carbonate gives washing soda which is a basic salt.
