The usual apparatus and reagents for qualitative work including the following with all reagents appropriately labelled;

- - (i) Dilute sodium hydroxide solution;
  - (ii) Dilute hydrochloric acid;
  - (iii) Dilute trioxonitrate
  - (V) acid;
  - (iv) Silver trioxonitrate
  - (V) solution;
  - (v) Acidified potassium dichromate solution;
  - (vi) Aqueous ammonia;

Each candidate should be supplied with the following, where ‘n’ is the candidiate’s serial number

150 cm3 of a solution of HCl in a corked flask or bottle labelled ‘An’. These should all be the same containing 8.5 cm3 of concentrated HCl per dm3 of solution.
150 cm3 of Na2CO3.10 H2O in a corked flask or bottle labelled ‘Bn’. These should all be the same containing 5.0 g of the hydrated salt per dm3 of solution.
One spatulaful of glucose in a specimen bottle labelled ‘Cn’. This must be the same for all candidates.
One spatulaful of zinc oxide powder in a specimen bottle labelled ‘Dn’. This must be same for all candidate
