Question

l1. which of the following aqueous solutions would be expected to be the best conductor of an electric current at room temperature? a. 0.10 M CH3COOH b. 0.10 M HCISrorb Acd C.0.10 M Na2SO4 d. 0.10 M NaCl e. 0.10 M H3PO4

Answer 1

Acidic solutions are not as better as ionic ones. CH₃COOH is a weak acid and cannot
dissociate completely, H₃PO₄ and HCl can dissociate very well but they are not as good as ionic ones
as they do not provide many ions as produced by Na₂SO₄ and NaCl.
Ionic aqueous solutions are great conductors of an electric current, among these options there are
only 2 such options i.e) 0.10M Na₂SO₄ and 0.10M NaCl. Na₂SO₄ has more ionzation per mole of substance
compared to NaCl hence, 0.10 M Na₂SO₄ is the best conductor.
Option c is the answer.
