(A) The answer is b. increases Electricity in the form of electrons are transported through the solution by charged ions of the electrolyte. As the electrolyte concentration increases, so does the number of charge carriers and hence the amount of charge and electricity conducted increases. (B) Acetic acid (CH3COOH) is a weak acid and partially ionizes in water: CH3COOH + H2O => CH3COO- + H3O+ The charged acetate (CH3COO- ) and hydroxonium (H3O+) ions are responsible for electrical conductivity. In 6 M acetic acid, water is in excess and and the ionization proceeds as shown above to give an electrolyte solution with charged ions that conduct electricity. In glacial acetic acid, there is very little water present and ionization is negliglble. Almost all the acetic acid remains in the non-conducting molecular form (CH3COOH) and there are no charged ions present. Thus glacial acetic acid does not conduct electricity.
