MR Investigating Rate of reply between Iodide ions and Peroxodisulphate ions with respect to Temperature and white plague of a Catalyst gate The aim of this experiment was to study the chance upon of the use of a catalyst and temperature on the browse of chemical reaction while belongings all the other factors that touch the reaction stride constant. In the reaction, potassium peroxodisulphate and potassium iodide will be used to bring home the bacon the peroxodisulphate ions and iodide ions respectively.
The ionic formula for the reaction is as follows: S2O82- (aq) + 2I- (aq) → 2SO42- (aq) + I2 (aq) However, in revision to measure the give birth into of reaction, sodium thiosulphate and starch are added. Sodium thiosulphate is added to react with a certain amount of atomic number 53 as it is made. Without the thiosulphate, the solution would go game blue/ filthy immediately, due to the iodine and starch. The thiosulphate ions leave behind the rate of reaction to be determined by delaying the reaction so that it is...If you want to get a full essay, order it on our website: Ordercustompaper.com
