Rate of reaction
The Effect of concentration on the reaction between magnesium and hydrochloric acid.
Mg(s) + 2HCl(aq) MgCl2(aq) + H2(g)
Aim:
In this experiment I am going observe and record the reaction between magnesium and different concentrations of hydrochloric acid.
Prediction:
I think that the high concentrations of acid such as 1.0 and 0.8mols we have the most rapid reaction and let off more gas a lot quicker. The weaker concentrations such as 0.2 will let off a smaller amount of CO2 because there is not much acid for the magnesium to react with.
Equipment:
