Chemical Properties of H2SO4

1. As an acid – It undergoes neutralization reaction.
H₂SO_4(aq) + 2NaOH_(aq) →  Na2SO_4(aq) + 2H₂O_(L)

2. As a dehydrating agent – It is able to remove water from compounds like sugar etc.
C₆H₁₂O₆ → 6C

3. It displaces other acids from their salts:-
H₂SO_4(aq) + 2NaCL_(aq) →  Na₂SO_4(aq) + 2HCL_(aq)
