We have presented substances, calcium oxide – CaO, zinc – Zn, hexavalent sulfur oxide – SO3, copper – Cu, trivalent iron hydroxide – Fe (OH) 3, silver nitrate – AgNO3, sodium chloride salt – NaCl. Consider which of these substances interact with hydrochloric acid, which has the chemical formula HCl.

A chemical reaction takes place between substances such as calcium oxide and hydrochloric acid. We get calcium chloride salt and water.

CaO + 2HCl = 2 CaCl2 + H2O

Reaction of zinc and hydrochloric acid. Zinc chloride and hydrogen salt are formed.

2 Zn + 2HCl = 2 ZnCl + H2

A chemical reaction takes place between substances such as ferric hydroxide and hydrochloric acid. Formed as a result of the reaction salt, ferric chloride and water.

Fe (OH) 3 + 3 HCl = FeCl3 + 3 H2O

Reaction of hydrochloric acid with silver nitrate salt. we get the silver chloride salt, which will precipitate and nitric acid.

AgNO3 + HCl = AgCl + HNO3.
