Magnesium reacts with dilute sulfuric acid.
Mg(s) + H2SO4(aq) → M9SO:(aq) + H2(g)
Two experiments are carried out at 25 °C.
experiment 1 24.0g of powdered magnesium is reacted with 100 cm3 of 1.0mol/dm3
sulfuric acid.
experiment 2 24.0g of powdered magnesium is reacted with 50 cm³ of 2.0 mol/dm3
sulfuric acid.
During each experiment the volume of hydrogen produced is measured. The results are plotted
on a graph.
