What factors affect the rate pf reaction between sodium thiosulphate and hydrochloric acid?
… this is when the reaction produces a precipitate which makes the solution cloudy. Observe a marker through the solution and measure how long it takes for it to disappear. – Change in mass; any reaction that produces gases can be put on a mass balance and as the gas is released the disappearing mass is easily measured. – Volume of gas released; this involves using a gas syringe to measure the volume to gas released in a reaction. For my experiment I am going to use the precipitation method to measure the rate of reaction between sodium thiosulphate and hydrochloric acid. This is because I am going to measure the time of the reaction between the two reactants and this is the most suitable method. Background in formation The reaction rate is the speed at which a reaction occurs; usually measured as the change in concentration of either reactants or products over time. For my …
