An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in

Concentrations of HCl on the Rate of Reaction Between HCl and Sodium Thiosulfate Chemistry Lab report Aim: The aim of this experiment is to determine how concentrations of HCl acid affect the rate of reaction when reacted with Sodium Thiosulfate (Na2S2O3). This experiment would require measuring the mass of the reaction over a period of time to be able to determine the rate of the reaction. Safety Precautions: In this experiment‚ SO2 gas is produced from the reaction between Sodium Thiosulfate and
