How Does Hydrochloric Acid Affect The Time Of Magnesium to Dissolve? Aim:         To find the relationship between the concentration of hydrochloric acid and the time taken by Magnesium to dissolve. Theory: Rates of Reaction -         Factors that alter speed of reactions. 1.         The temperature of reactants: reactions are faster when the temperature is raised, and slower if the temperature drops. 2.         The concentration of dissolved reactants (that is how much of the reactant is dissolved in a …showed first 75 words of 1494 total…

I did realise this, and changed the beaker to make sure the other tests went fairly. Other than this, the experiment was as accurate as possible.         I think the experiment could be improved. If I had some more results, it could increase the accuracy and reliability of the tests.
