To carry out the above chain of transformations, it is necessary to carry out the following reactions:
The reaction between sulfuric acid and aluminum, as a result of the reaction, aluminum sulfate and hydrogen are formed.
3 H2SO4 + 2 Al = Al2 (SO4) 3 + 3 H2
The next reaction is the reaction of obtaining water from oxygen and hydrogen.
2 H2 + O2 = 2 H2O
We add calcium to the water, as a result of the reaction, calcium hydroxide is formed and hydrogen is released.
2 H2O + Ca = Ca (OH) 2 + H2
