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.
