- (b) one pipette, either 20cm3 or 25cm3.
- (c) The usual apparatus for titration
- (d) the usual apparatus and reagents for qualitative work including the following with all reagents appropriately labelled.
Others includes
- (i) glass rod
- (ii) aqueous ammonia
- (iii) dilute hydrochloric acid
- (iv) dilute sodium hydroxide solution
- (v) barium chloride solution
- (vi) dilute trioxonitrate (V) acid

- (viii) dilute tetraoxosulphate (VI) acid
- (e) glass rod
- (f) filtration apparatus
- (g) spatula
- (h) two boiling tubes
- (f) four test tubes
- (g) wash bottle containing distilled/deionized water
- (h) mathematical table/calculator.
QUESTIONS II
(2) Equally important, each candidate should be supplied with the following, where ‘n’ is the candidate’s serial number.
(a) 150cm3 of ethanedioic acid (H2C204) solution in a corked flask or bottled labelled ‘An’.
As a matter of fact, these should all be the same containing 4.50g of H2C204 per dm3 of solution.
(b) 150cm3 of potassium tetraoxomanganate (VII) solution in a corked flask or bottle labelled ‘Bn’.
However, these should all be the same containing 3.16g of KMnO4 per dm3 of solution.
(c) One spatulaful of a uniform mixture of NaCl and ZnCO3 in a specimen bottle labelled ‘Cn’.
On the other hand, the components of the mixture should be in the ratio 1:1 by mass.
