Rate of reactions Aim The aim of this experiment is to find out what effect the concentration of hydrochloric acid has upon the rate of the reaction with magnesium. Prediction I predict that the higher the concentration of the acid, the more hydrogen gas will be produced. The reason for this prediction is that there will be more chlorine molecules to react with the magnesium molecules, releasing the hydrogen gas. For every magnesium molecule, 2 hydrogen atoms are released as a hydrogen molecule. The reason why magnesium reacts with hydrochloric acid to release hydrogen is because Magnesium is much more reactive than hydrogen there fore the magnesium molecules displace the hydrogen as a gas leaving magnesium chloride in the conical flask. Mg + HCl2 › MgCl2 + H2 Magnesium + Hydrochloric acid › Magnesium Chloride + Hydrogen Fair testing I will keep this experiment as fair as possible by following these few guidelines: 1. I will use the same...
