Question
In the Lime – Caustic Soda” process, the reactants are:
- Ca (OH)2 and NaOH
- Ca (OH)2
- NaOH
- CaO and NaOH
Hint:
Lime is calcium hydroxide and caustic soda is sodium hydroxide.
The correct answer is: Ca (OH)2 and NaOH
- Lime-soda process is water softener system.
- In this process calcium hydroxide and soda ash is used as reagent.
- Soda ash is prepared from caustic soda.
- Hence in the Lime – Caustic Soda” process, the reactants are Ca(OH)2 and NaOH.
