Question

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.
