Investigating Reaction Rates Problem: To investigate a factor which affects the rate of reaction between magnesium ribbon and hydrochloric acid. Initial Investigation: The reaction that takes place is Magnesium and hydrochloric acid. Magnesium + Hydrochloric Acid „³ Magnesium chloride + hydrogen Mg + HCl „³ MgCl2 + H2 Magnesium reacts with the hydrochloric acid to give magnesium chloride and hydrogen. We saw fizzing due to hydrogen gas being given off. The magnesium strip dissolved to give a clear solution. To measure the rate of the reaction we time the reaction then...
on the results.

All of the results I obtained were exactly as expected in my prediction and I think they would be good enough to convince other people.

Now I am going to look at another way of proving my results are correct by doing the same experiment again only this time using a different metal and a different acid, zinc and sulphuric acid.

Zinc + Sulphuric acid „³ Zinc sulphate + hydrogen

Zn + H2SO4 „³ ZnSO4 + H2

The results of this experiment should prove my results weren¡¦t a fluke.
