Sodium Thiosulphate GCSE Coursework The aim of these experiments is to investigate how concentration affects the rate of reaction between two chemicals. Planning For our investigation we will be using Sodium Thiosulphate and Hydrochloric Acid. We chose these chemicals, because visual changes take place when the two are mixed together. Combining them will produce a yellow precipitate, and this will make it easy for us to measure the rate of reaction. To investigate the effect concentration has on reaction rates, we must vary the concentration of one of the two chemicals used. Sodium Thiosulphate and Hydrochloric Acid are both soluble in water, so it would be possible to alter the concentration of either of them. However, we have decided to vary the concentration of the Sodium Thiosulphate because [REASON]. To measure the rate of reaction, we will be using light sensors connected to a computer. The solution of Thiosulphate will be poured into a...
