Question

In the Chemistry lab the teacher told the students to label some electrolytes suitably. The labelling given by one student is as given: 

Strong electrolyte – H₂SO4 , NH₄OH, KOH, Ca(OH)₂

Weak electrolytes – NaOH, HCN, NaCl, HCl

1. Is it correct? Justify.

2. Correct it.

3. What do you mean by electrolysis?

Answer 1

1. No.

2. Strong electrolytes – H₂SO₄ , KOH, HCl, NaOH, NaCl

Weak electrolytes – NH₄OH, HCN,Ca(OH)₂

3. The process of chemical decomposition of electrolyte by the passage of electricity through its molten or dissolved state is called electrolysis.
