An investigation to show how we can change the rate of the reaction between magnesium and hydrochloric acid. Planning During my science lessons I have learnt the following information that has enabled me to plan my investigation. As a substance becomes less concentrated there are less particles of that substance in a given space. The greater the concentration of particles the greater the chance they have of colliding with each other. When particles of magnesium and hydrochloric acid collide they can either bounce apart or react to form a new substance. If they collide more often they will react more often. Therefore decreasing the concentration of hydrochloric acid decreases the rate of the reaction. Prediction On the basis of my research, I predict that as you change the concentration it will affect the rate of the reaction. So the greater the concentration of particles the greater the rate of the reaction will be. The...
