INVESTIGATING THE EFFECT OF ALTERING THE CONC. OF HCl ON THE RATE OF REACTION By Nazmul Akunjee 5C Teacher - Mr. Cotton Plan: - In order to create a fair test, it is important that we only vary one variable while keeping the other variables constant. The continuous variables within this practical include - ? The temperature ? The concentration of the magnesium ? The concentration of the acid ? The surface area of the magnesium ? The pressure of the experiment The dependent variables within this practical include - ? Amount of magnesium chloride produced ? Volume of Hydrogen produced I will investigate the effect of concentration of HCl which will be added to the magnesium to release hydrogen. The equation of the formula that will take place in experiment is: For the above reaction to take place there must be an effective collision between the two substances, i.e. magnesium and HCl molecules. For the effective collision to occur the...
