How does the concentration of sodium thiosulphate influence speed of reaction with dilute hydrochloric acid? Aim: I am investigating how the concentration of sodium thiosulphate influences the speed of reaction with dilute hydrochloric acid. Equipment * 1 piece of paper with a cross on it * 1 timer * 1 conical flask 100ml * 1 test tube brush * 119ml Sodium thiosulphate * 14ml 100% Hydrochloric acid * 1 beaker 400ml * 1 beaker 10ml 1. Working with the first dilution I will measure out the solution and place the Sodium thiosulphate in the conical flask positioned on top of the paper so the cross is visable from above, through the neck of the flask. Then I will measure out and add the water needed in that dilution. 2. As I pour the hydrochloric acid, measured out in the 10ml, beaker into the conical flask, I will start the timer. 3. I will look vertically down through the neck of the...
