Question

Classify the following :
1)$HCl$
2) $C{H}_{3}COOH$
3) $C{H}_{3}COONa$
4) Rubber
5) Common Salt
M- Strong Electrolyte N- Weak Electrolyte
O - Non-Electrolyte

• A. M – 1, 2; N – 3,4; O – 5
• B. M – 1, 2, 3, 5; O – 4
• C. M – 1, 3, 5; N – 2; O – 4
• D. M – 1, 2, 3; N – 4; O – 5

Answer 1

The correct option is C M – 1, 3, 5; N – 2; O – 4

$HCl$ is strong acid so it is a strong electrolyte.
$C{H}_{3}COOH$ is a weak acid and dissociates partially so it is a weak electrolyte.
While $C{H}_{3}COONa$ is an ionic salt, so it is a strong electrolyte as it completely dissociates.
Same with common salt as it is an ionic salt, it is a strong electrolyte
Rubber which is a polymer doesn’t at all dissociates, so it is a non electrolyte.
