Science course Aim The aim of this practical is to investigate how changing concentration will affect the rate of reaction between magnesium and hydrochloric acid. Prediction I think that the higher concentration of hydrochloric acid will increase the likelihood of chemical collisions between hydrochloric acid and magnesium. This increase in chemical collisions will produce much faster chemical reaction. The rate of a reaction between magnesium and hydrochloric acid refers to the speed of the reaction. It is not how much of a product is made, but instead how quickly a reaction takes place. How quickly a reaction takes place depends on firstly, how quickly one of the products (e.g. the hydrogen) is made, secondly how quickly one of the reactants (e.g. hydrochloric acid) disappears. The collision theory explains how different variables change the rate of reaction, the four main variables that can change the rates of reaction includes: The concentration of the...
