In a titration experiment, 22.50 cm3 of an acid solution A containing 10.6 g of NaHSO4 per dm3 reacted with 25.0 cm3 of solution B containing X g of NaOH per dm3.
The equation for the reaction is:
NaHSO4(aq) + NaOH(aq) Na2SO4(aq) + H2(l)
(a) From the information given above, calculate the:
(i) concentrate of A in moldm– 3;
(ii) concentrate of B in moldm– 3;
(iii) value of X;
(iv) mass of Na2SO4 formed during the reaction.
[ H = 1.00; 0 = 16.0; Na = 23.0; S = 32.0] (16 marks)
(b)
(i) Name a suitable indicator for the titration
experiment.
(ii) State the apparatus used to measure the
volume of solution:
I. A;
II B; (3 marks)
