What oxides, when interacting with hydrochloric acid, are converted into the following salts: CaCl2, HgCl2, FeCl3
| February 17, 2021 | education
In this task, we will determine the oxides that form salts CaCl2, HgCl2, FeCl3 when interacting with hydrochloric acid.
CaO + 2HCI = CaCl2 + H2O.
When calcium oxide interacts with hydrochloric acid, the result is calcium chloride and water. The reaction is called an exchange reaction or neutralization.
HgO + 2HCl = HgCl2 + H2O.
In this reaction, an interaction occurs between hydrochloric acid and mercury oxide, resulting in the formation of mercury chloride and water.
Fe2O3 + 6HCI = 2FeCl3 + 3H2O.
When iron oxide and hydrochloric acid react, ferric chloride and water are formed.
