Answer #1

As per neutralisation equation, 1 molecule of acid combines with 2 molecules of KOH.

Number of moles of acid

Number of moles of KOH

number of moles of acid

Molarity of KOH is 0.69 mol/L.

Volume of KOH required

Convert unit from L to mL

Hence, 128 mL of 0.69 M KOH solution is needed to completely neutralise the acid.
