Investigating the effect of changing the concentration of acid on the rate of reaction of Magnesium and Hydrochloric acid. Aim - the investigation will test whether changing the concentration of Hydrochloric acid has an effect on the rate of reaction when it is added to a strip of Magnesium. Prediction - I predict that the rate of the reaction will increase as the concentration of the Hydrochloric acid is increased. I have made this prediction based on my knowledge of the collision theory. This theory states that when there is a higher concentration of something, there will be more particles of that object in the same area (see diagram below). Therefore the particles will have less space to move around, and increase the number of collisions. All the variables in the experiment all relate to the collision theory in some way In this experiment, there are many variables, but the concentration of...
