In this task, you should write down the chemical reaction equations for the next chain of transformations. We write down the received.
Cl2 -> HCl -> NaCl -> Cl2 -> KCl -> AgCl.
1. Reaction of the compound.
H2 + Cl2 = 2HCl.
When hydrogen interacts with chlorine, hydrogen chloride is formed.
2. Reaction of exchange.
HCl + NaOH = NaCl + H2O.
When hydrochloric acid and sodium hydroxide interact, sodium chloride and water are formed as a result.
3. Reaction of exchange.
2NaCl + 2H2O = Cl2 + H2 + 2NaOH.
When sodium chloride and water interact, the result is chlorine, hydrogen and sodium hydroxide.
4. Substitution reaction.
Cl2 + 2KBr = 2KCl + Br2.
The interaction of chlorine and potassium bromide forms potassium chloride and bromine.
5. Reaction of exchange.
KCl + AgNO3 = AgCl + KNO3.
The result is potassium nitrate and silver chloride precipitates.
