They must NOT start writing during this time.) ---------------------------------------------------------------------------------------------------------------ALL ANSWERS MUST BE WRITTEN IN THE ANSWER BOOKLET PROVIDED SEPARATELY. Question 1 is an oxidation-reduction titration in which sufficient working details are given. All essential working must be shown. Question 2 is an exercise dealing with the identification of organic compound and distinction between carbohydrates and proteins. Credit will be given for precise observations recorded and for well drawn deductions. Question 3 is an exercise in qualitative analysis. ---------------------------------------------------------------------------------------------------------------Read the questions carefully and follow the given instructions. Attempt all questions. All working, including rough work, should be done on the same sheet as the rest of the answer. The intended marks for questions or parts of questions are given in brackets [ ]. Mathematical Tables are provided. ---------------------------------------------------------------------------------------------------------------Attempt all questions. Question 1 [8] You are provided with two solutions as follows: C-10 is a solution prepared by dissolving 1.04 gms of potassium manganate (VII) KMnO4 per litre. C-11 is a solution prepared by dissolving 13.4 gms of hydrated ammonium iron (II) sulphate crystals, (NH4)2SO4.FeSO4.xH2O per litre. PROCEDURE: Rinse and fill the burette with the solution C-10 (KMnO4). Pipette out 20 ml or 25 ml of C-11 (hydrated ammonium iron(II) sulphate) into a clean conical flask. To this, add 20ml of dilute sulphuric acid C-12, specially provided for titration. Titrate the solution with C-10 (KMnO4) till one drop of this gives a light permanent pink colour to the solution in the conical flask. Ensure that the pink colour does not disappear on shaking the contents of the conical flask. Repeat the experiment to get at least two concordant readings. ---------------------------------------------------------------------------------------------------------------------------56 ISC SPECIMEN QUESTION PAPER 2015
