How does the concentration of acid affect the rate of a reaction? Aim In this experiment I aim to find out the rate of reaction of magnesium in different concentrations of sulphuric acid. Diagram List Of Equipment Clamp Gas Syringe Magnesium Conical flask Sulphuric acid Stopwatch (1M) Method 1. Set-up equipment as in the diagram except keep the magnesium out of the acid. 2. Place the magnesium inside the conical flask and start the stopwatch at the same time. 3. Record the amount of gas produced every 5 seconds. 4. Repeat with 0.8M, 0.6M, 0.4M and 0.2M acid. Fair Testing * I must keep the amount of sulphuric acid I use the same because it might speed up the reaction * I must keep the length of the D-tube the same because the gas has to travel from one end to the other. * I must keep the temperature the same because I know from my research that increased temperature means a faster reactions...
