1 The relative molecular mass of a solid dicarboxylic acid, HOOC(CH2)nCOOH, can be
found using a titration. The acid, which can be represented as H2A, was dissolved in
deionised water and the solution made up to 250 cm3.
(a) Which piece of apparatus should be used for making a solution with a volume of
exactly 250 cm3 ?
(1)
A burette
B measuring cylinder
C pipette
D volumetric flask

(b) A solution of 0.100 mol dm–3 sodium hydroxide solution was added to a burette.
A rough titration was carried out on a 25.0 cm3 portion of the acid solution.
