Aim: In this coursework I aim to investigate whether changing the concentration of Hydrochloric acid and Distilled water will affect the reaction time in which it takes to dissolve an amount of magnesium strips. Introduction: The experiment we have conducted as part of our GCSE Coursework is a neutralisation reaction. Before starting the investigation, I decided to do some research about magnesium and Hydrochloric acid. Magnesium is a light, shiny grey metallic element and it’…showed first 75 words of 264 total…

If the collision between particles can produce sufficient energy (i.e. if they collide fast enough and in the right direction) a reaction will take place. The reaction however can be speeded up if the number of collisions is increased.
