Chemistry Coursework Rate of reaction Aim: Plan an investigation into the rate of reaction between Sodium thiosulphate and hydrochloric acid. Background information: • The equation for the rate of reaction is 1/time. • The rate of reaction measures the speed of reaction. It is ...

Introduction In this investigation I am trying to find out whether or not the concentration of hydrochloric acid affects the rate of reaction. To do this we are going to make up different concentrations of hydrochloric acid starting with 100% and working our way to 20%. Prediction I predict th...

We were asked to extract benzoic acid from a kerosene-benzoic acid mixture. This was to be done using the stirred liquid-liquid extraction column in the senior laboratory. Fresh water was used as the continuous phase in the extraction. We were asked to measure the benzoic acid concentrations of...
