Answer 1

Correct Question : How is washing soda obtained ? Write equation to represent this.

Answer : Washing soda can be obtained by heating baking soda. On heating, baking soda gives sodium carbonate, carbon dioxide and water. Consequently, the recrystallisation of sodium carbonate gives washing soda.

Equation is in above pic.

Extra information : Sodium carbonate, (washing soda) Na₂CO₃, is the inorganic compound with the formula Na₂CO₃ and its various hydrates. All forms are white, water-soluble salts that yield moderately alkaline solutions in water. Historically it was extracted from the ashes of plants growing in sodium-rich soils.

Formula: Na2CO3

Molar mass: 105.9888 g/mol

Density: 2.54 g/cm³

Melting point: 851 °C

Boiling point: 1,600 °C

Soluble in: Water
