Substances are given: sodium hydroxide, hydrochloric acid, calcium oxide, water. Which of these substances will interact with each other? Write the reaction equations and name the resulting substances.

We are presented with the substances sodium hydroxide – NaOH, hydrochloric acid – HCl, calcium oxide – CaO and water – H2O.

These chemicals interact with each other as follows:

Sodium hydroxide reacts with hydrochloric acid. We get sodium chloride salt and water.

NaOH + HCl = NaCl + H2O
A chemical reaction takes place between substances such as hydrochloric acid and calcium oxide. Formed salt calcium chloride and water.

2 HCl + CaO = CaCl2 + H2O
Lime slaking reaction. it is the interaction of calcium oxide and water. We get calcium hydroxide.

CaO + H2O = Ca (OH) 2.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
