Question

Which of the following compounds in their aqueous or molten state are correctly categorized below:

• A. Strong electrolyte:- $NaCl$ Weak electrolyte:- $C{H}_{3}COOH$
• B. Strong electrolyte:- $C{H}_{3}COOH$ Weak electrolyte:- $HCl$
• C. Strong electrolyte:- $N{H}_{4}OH$ Weak electrolyte:- $HCl$
• D. Strong electrolyte:- $NaCl$ Weak electrolyte:- $N{H}_{4}OH$

Answer 1

Answer: (A), (D)

The correct options are
A

Strong electrolyte:- $NaCl$

Weak electrolyte:- $C{H}_{3}COOH$

D

Strong electrolyte:- $NaCl$

Weak electrolyte:- $N{H}_{4}OH$

Electrolytes are the compounds which in their aqueous or molten state conduct electric current through them because they contain free mobile ions.

Strong Electrolytes:- They dissociate almost completely into ions in their aqueous or molten state. Example:- Sodium Chloride $NaCl$, hydrochloric acid $HCl$ etc.

Weak Electrolytes:- They partially dissociate into ions in their liquid states. Example:- Ammonium hydroxide $N{H}_{4}OH$, acetic acid $C{H}_{3}COOH$ etc.
