FAQs on Reaction of Metal Oxides with Acids Video Lecture - Class 10

1. What happens when metal oxides react with acids?

Ans. When metal oxides react with acids, they undergo a chemical reaction to form a salt and water. This process is known as neutralization.

2. Which gases are evolved when metal oxides react with acids?

Ans. When metal oxides react with acids, the gases that are commonly evolved are carbon dioxide (CO2) and sulfur dioxide (SO2), depending on the specific metal oxide and acid involved in the reaction.

3. What is the role of metal oxides in acid-base reactions?

Ans. Metal oxides act as bases in acid-base reactions. They neutralize the acidic properties of the acids and form salts, which are neutral compounds. This reaction helps to balance the pH levels and reduce the acidity of the solution.

4. Can all metal oxides react with acids?

Ans. Not all metal oxides can react with acids. Only metal oxides that have basic properties can react with acids to form salts and water. Metal oxides that are amphoteric or acidic in nature may not undergo this reaction.

5. How do metal oxides and acids play a role in daily life?

Ans. Metal oxides and acids play significant roles in daily life. For example, the reaction between metal oxides like calcium oxide (CaO) and sulfur dioxide (SO2) produced by burning coal helps in reducing air pollution. Additionally, the reaction between metal oxides and acids is used in various industrial processes such as manufacturing salts, cleaning metal surfaces, and producing fertilizers.

Text Transcript from Video

we will see what happens when metal
oxides react with an acid we need test
tube copper oxide and dilute
hydrochloric acid take some copper oxide
in the test tube a dilute hydrochloric
acid to it drop by drop and shake you
will see the solution has turned green
the copper which was in insoluble form
in copper oxide has reacted with
hydrochloric acid and formed a soluble
salt with the chloride ion from the acid
and formed copper chloride the solution
now contains copper chloride when metal
oxides react with an acid metal oxides
form a salt with the negative ion of the
acid in this case the reaction can be
depicted as Cu o plus 2 HCl gives cocl 2
plus h2o
