Question

What is the volume (in litres) of 0.1M H2SO4
required to completely neutralize 1 litre of
0.5M NaOH?

Answer 1

Amount of NaOH in 1 L 0.5 M NaOH = 0.5 mol, as molarity is nothing but the number of moles present per litre. Thus, 1 mol NaOH needs 0.5 mol H2SO4. Here, we need 0.5 X 0.5 = 0.25 mol of the acid. Now, 1 L of the acid solution has : 0.1 mol of the acid.
