Doron Hershkorn 10ww science coursework Chemistry "The effect of varying the concentration of the reaction between magnesium and hydrochloric acid". Aim: The aim of this investigation is to find out the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. It is important to remember that a rapid reaction is completed in a short period of time. Some reactions are very fast, For example (the formation of silver chloride precipitate when silver nitrate and hydrochloric acid solutions are mixed).In this investigation we will test different concentrations of acid reacting with magnesium. Prediction: I predict that as the concentration of the hydrochloric acid increases, the time taken for the magnesium to disappear decreases. I predict that when the concentration of the hydrochloric acid doubles, the rate of the reaction doubles. Linking...
