PLANNING Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions‚ then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction

Matter is anything that has a mass and takes up space. There are many ways to describe matter using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance

Our primary aim was to demonstrate the different techniques needed to isolate biosynthetic auxotrophic mutants using chemical‚ physical and transposon mutagenesis. The second aim was to plan and execute an experiment designed

collected and washed with hexane through a series of processes involving vacuum filtration. Then a mixture of 5mh of the crystals and 5ml of 95% ethanol was created and tested on a slice of potato to analyse the iodine content. After‚ with sodium thiosulphate in the buret‚ the iodide solution was titrated until it turned orangey-yellow‚ then had 2ml of starch added to it and titrated again until it turned colourless.

to the reaction – sodium thiosulphate (Na2S2O3) and starch. The S2O32- ion reacts with any iodine produced in the first reaction according to the following equation: 2S2O32-(aq) + I2(aq) S4O62-(aq) + 2I-(aq) Because we add a known volume of thiosulphate to the equation‚ we can work out the number of moles of thiosulphate that reacts with iodine‚ and therefore work out the number of moles of iodine that reacts. The starch acts as an indicator – when all of the thiosulphate has been used up

at the color shown by the addition of starch solution. Iodine also reacts with sodium thiosulphate solution‚ which acts as a delaying agent. Adding sodium thiosulphate to the reaction mixture will allow the iodine produced initially to react with the thiosulphate ions‚ which reduce the iodine to iodide ions‚ leaving the starch unchanged. 2S2O32-(aq) + I2 (aq) S4O62- (aq) + 2I- (aq) Once all the thiosulphate ions have reacted with the iodine‚ the iodine will then go on to react with the
