Science Coursework In my coursework I want to find out and investigate how changing concentration of hydrochloric acid affects Rate of Reaction with Magnesium. In my coursework I am going to change the concentration of Hydrochloric acid which is the variable of this experiment. The different types of Moles I am going to use are; 1M, 1.5M, 2M, 3M and 4M. My prediction for this coursework is when I increase acid concentration the Rate of Reaction increases. This is because it has more particles in the concentration so it will collide with other atoms. Qualitive Prediction, if I double the acid concentration there will be double the particles in the concentration which will double the collision between the particles. In my experiment I should also keep other variables same to make sure I have a fair test in my experiment, the variables that I need to look for are; Temperature, I...
