Draw the Lewis Dot structure for the following diprotic acid: HOOC-CH2-COOH. 38.5 mL of a 1.15 M solution of this acid is titrated to the equivalence point with 0.69 M KOH. Write the balanced equation for this reaction and determine the volume of base needed to completely neutralize the acid
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.
