Reaction equation: Br2 ← Cl2 → NaCl → HCl → AlCl3 → Al (OH) 3

In this task you need to write down the equation of chemical reactions for the following chain of compounds.

Br2 ← Cl2 → NaCl → HCl → AlCl3 → Al (OH) 3.

Substitution reaction.

Cl2 + 2NaBr -> 2NaCl + Br2.

When chlorine interacts with sodium bromide, the result is sodium chloride and bromine.

Addition reaction.

Cl2 + 2Na = 2NaCl.

When chlorine interacts with sodium, the result is a sodium chloride salt.

Exchange reaction.

NaCl + HNO3 = HCl + NaNO3.

When sodium chloride interacts with nitric acid, hydrochloric acid and sodium nitrate are formed as a result.

Substitution reaction.

6HCl + 2Al = 2AlCl3 + 3H2.

When hydrochloric acid reacts with aluminum, aluminum chloride and hydrogen are formed.

Exchange reaction.

AlCl3 + 3NaOH = Al (OH) 3 + 3NaCl.

When aluminum chloride interacts with sodium hydroxide, aluminum hydroxide and sodium chloride are formed.
