(b) Electrolyte and Metallic conductor (the particles conducting electricity)
(a) Acetic acid and Sulphuric acid (number of replaceable hydrogen ion per molecule)
(b) Electrolyte and Metallic conductor (the particles conducting electricity)
Show Hint
In acetic acid, although there are four hydrogen atoms in total, only the one attached to the oxygen atom in the carboxyl group ((-COOH)) is ionizable!

Solution and Explanation
(a) Acetic acid vs Sulphuric acid (number of replaceable hydrogen ions):
Acetic acid (CH3COOH) is a monobasic acid.
It has only one replaceable hydrogen ion (H+) per molecule.
Sulphuric acid (H2SO4) is a dibasic acid.
It has two replaceable hydrogen ions (2H+) per molecule.
(b) Electrolyte vs Metallic conductor (particles conducting electricity):
In an electrolyte, electricity is conducted by the movement of ions (both cations and anions) in molten state or aqueous solution.
In a metallic conductor, electricity is conducted by the flow of free electrons within the metal lattice.
Final Answer:
(a)
Acetic acid → 1 replaceable H+ (monobasic)
Sulphuric acid → 2 replaceable H+ (dibasic)
(b)
Electrolyte → conduction by ions
Metallic conductor → conduction by free electrons
