CHEMISTRY TEST ASSIGNMENT

The test is divided into two different section Section 1: Numerical – 30 Marks Section 2: Theoretical – 20 Marks

Total Marks: 50

Section 1 – Numerical

1. We have about 10g of Iron(II) ammonium sulphate crystals. We mix these and make a

20cm3 acidified solution of this. Approximately 21.25cm ³ of potassium dichromate(VI) (0.02 mol dm^-3) is needed for oxidation of 25cm³ of. the solution made.

Given the formula of crystal as442

The value of a+b+c+x is?

2. We have an iodine solution (25cm³). It is titrated with sodium thiosulfate (0.1 mol dm^-3). With this, around 17.6cm³ of iodine solution reacted. The concentration of iodine is

then found out to be x mol dm^-3 and y g dm^-3.

Evaluate: (y – x)?

Section 2 – Theoretical
