Preliminary Experiment Aim My aim is to investigate the factors that affect the rate of reaction. I will be seeing how the concentration of the hydrochloric acid affects the rate of reaction with magnesium ribbon. Diagram Risk Assessment * Be careful whilst using the acids * Make sure all glassware is safely on the table to prevent it from falling off * Be careful whilst using the scissors Method 1. ...read more.

Check the syringe for any leaks by pulling it and seeing if it goes back to 0. Make sure that is at 0 to begin with. 2. Measure out 50mls of hydrochloric acid in a conical flask. 3. Add 2cm of magnesium ribbon to the solution, place the bun on the top and start the timer. ...read more.

Conclusion

After 20secs (cm3) C0 ? After 40secs (cm3) 50ml 0ml 15 16 30ml 20ml 4 6 25ml 25ml 3 5 Conclusion The more concentrated the solution is, the more C0? is given off after a shorter time span. This means that the concentration of a solution affects the rate of reaction. However, to make sure that this presumption is correct I will do a further experiment, using a more varied range and repeats. ...read more.
