Question

Question: Classify the following substances as strong electrolytes, weak electrolytes, or non-electrolytes:

(a) Sodium permanganate (NaMnO₄)

(b) Acetic acid (CH₃COOH)

(c) Methanol (CH₃OH)

(d) Calcium acetate [Ca(C₂H₃O₂₎₂]

Short answer

Answer

(a) Sodium permanganate$\left(NaMN{O}_4\right)$is astrong electrolyte

(b) Acetic acid$\left(C{H}_{3}COOH\right)$is a weak electrolyte

(c) Methanol$\left(C{H}_{3}OH\right)$is non electrolyte

(d) Calcium acetate $\left[\mathbf{Ca}{\left({\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}_{\mathbf{2}}\right)}_{\mathbf{2}}\right]$is a strong electrolyte

Step-by-step solution

sodium permanganate

Sodium permanganateis a strong electrolyte (NaMnO₄) because it almost completely ionizes or dissociates in a solution. It effectively conducts electricity.

Acetic acid  

Acetic acid is a weak electrolytebecause it only partially ionizes in a solution. They are weak conductor of electricity

Methanol

Methanol is a non-electrolyte because it does not have any distinct ionic form and do not ionize in a solution. They are poor conductors of electricity.

calcium acetate  

Calcium acetate$\left[\mathbf{Ca}{\left({\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}_{\mathbf{2}}\right)}_{\mathbf{2}}\right]$is a strong electrolyte because it almost completely ionizes or dissociates in a solution. It is a good conductor of electricity.
