Hydrogen can be obtained by the interaction of aluminum with solutions of hydrochloric and sulfuric acid. Make up the equations of these reactions.
The reaction of aluminum with acids (dilute hydrochloric and sulfuric) refers to substitution reactions. This is possible due to the fact that aluminum is located to the left of hydrogen in the row of electrochemical activity of metals, thereby quietly displacing hydrogen from acids. 2 Al + 6 HCl (dil.) => 2 AlCl3 + 3 H2 ↑ 2 Al + 3 H2SO4 (dil.) => Al2 (SO4) 3 + 3 H2 ↑
