Statement I : 1 mole of

{H_2}S{O_4}

is neutralised by 2 mol of NaOH but 1 equivalent of

{H_2}S{O_4}

is neutralised by 1 equivalent of NaOH
Statement II : Equivalent amount of

{H_2}S{O_4}

is the quantity that is equal to 1 g H and hence, each mol of

{H_2}S{O_4}

is equal to 2 equivalents of

{H_2}S{O_4}

Which statement(s) is/are correct ?

View answer and explanation

Correct option: C

Both I and II

Option C (Both I and II) is correct because 1 mole of H2SO4 requires 2 moles of NaOH for neutralization, and the equivalent amount of H2SO4 is indeed the quantity that is equal to 1 g H, meaning each mole of H2SO4 is equal to 2 equivalents.
