An Investigation to show how concentration changes the speed of reaction between magnesium and hydrochloric acid. Planning 1: The aim of this investigation is to find out the effect of acid concentration 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. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different concentrations of acid reacting with magnesium in two separate experiments, which will hopefully prove this initial prediction. During my science lesson I have learnt the following information that has enabled me to plan my investigation. Using my science book as evidence, I feel that as I continue to add water to the hydrochloric acid, its concentration decreases. Therefore the less acid molecules there are the smaller the...
