Aim: - My aim is to investigate the effect of concentration on the rate of reaction. I will be changing the concentration of dilute hydrochloric acid. Hypothesis: - As the concentration of dilute hydrochloric acid increases, it shall speed up the rate of reaction. Apparatus: - Magnesium Ribbon, 0.5 mol/dm³, 1.0 mol/dm³, 1.5 mol/dm³, and 2.0 mol/dm³ of dilute hydrochloric acid, Stopwatch, Measuring Cylinder, Thermometer, Gas Syringe, clamp and stand, and a beaker with a bung, Conical Flask Health and Safety: - 1. Make sure safety specs are worn all the time. 2. Tie back hair. 3. Wear a lab coat. 4. Any spillages should be cleaned up straight away. Method: - 1. Put on a lab coat, safety specs, and tie back loose hair. 2. Assemble the gas syringe, clamp, and stand, with the beaker and the bung. 3. Measure out 50cm ³ of dilute hydrochloric acid of the concentration 0.5mol/dm ³ using a measuring cylinder and pour into a conical flask which is attached to the gas...
