       (e) glass rod;
       (f) filtration apparatus,
       (g) spatula,
       (h) two boiling tubes,
       (i) four test tubes,
       (j) wash bottle containing distilled/deionized water,
       (k) mathematical table/calculator.
       +Each candidate should be supplied with the following, where ‘n’
       is the candidate’s serial number.
       (a) 150cm³ of potassium tetraoxomanganate(VII)solution in a

       same containing 7.7g of KMnO4 per dm³ of solution.
       (b) 150cm³ of iron(II)chloride solution in a corked flask or
       bottle labelled ‘Nn’. These should all be the same containing
       19.1g of FeCl2 per dm³ of solution.
       NB- FeCl2 solution should be freshly prepared.
       – Each candidate should be provided with 150cm³ 2M H2SO4.
       (c) One spatulaful of copper(II)chloride in a specimen bottle
