​

Answer 1

Answer:

Washing soda :-  Sodium, carbon, oxygen and hydrogen.

Sugar:- Carbon, hydrogen and oxygen.

Caustic soda:- Sodium, oxygen and hydrogen.

Explanation:

Washing soda  (Na₂CO₃.10H₂O) contains Sodium, carbon, oxygen and hydrogen elements.

• Washing soda is manufactured by Solvay’s process. This process involves the reaction of sodium chloride, carbon dioxide and ammonia in water.

• In this process first sodium bicarbonate is obtained. On heating it is converted into sodium carbonate. Washing soda is obtained by recrystallization of sodium carbonate (NaHCO₃).

Sugar:-

• Sugar also known as table sugar is a disaccharide. It consists of two monosaccharide which are fructose and glucose. The  molecular formula for sucrose is C₁₂H₂₂O₁₁. Each sugar molecule contains 12 carbon atoms, 11 oxygen atoms, and 22 hydrogen atoms.

Caustic soda :-

• Caustic soda also called Lye is an alkali salt . Actually, Caustic soda is the common name of sodium hydroxide. This name is given to it due to the corrosive nature of this salt on plant tissues and animal tissues. As we know, the chemical formula of sodium hydroxide is NaOH. Therefore the  elements in Caustic soda are Sodium, oxygen and hydrogen.
