Question

1: F is a solution of NaOH containing 0.0500 mol of the
alkali in 500 cm3 of solution.

G is a solution of a monobasic acid, HY.

(a) Put solution G into the burette.
Titrate 25.0 cm3 portions of F against Gusing
phenolphthalein as indicator.
Assuming the Average Titre Value of G is 23.30cm3

The equation of reaction is:
NaOH(aq) + HY(aq) NaY(aq) +

H2O(l)

(b) From your results and the information

provided, calculate the:
(i) concerntration of F in moldm-3;
(ii) concerntration of G in moldm-3;
(iii) molar mass of the acid, HY if the concentration of
acid in solution G is 3.95 gdm-3
(iv) relative atomic mass of Y;
(v) percentage by mass of Y in HY. [H = 1.00]
