Описание: Burning of Magnesium Ribbon 🎗️ Science Activity class 10th ||Activity 1.1 Chemistry

Aim
To carry out the Burning of magnesium ribbon in air and classify it as physical and chemical changes.

Materials Required
Magnesium Ribbon, Burner, Tongs, Watch Glass, pH paper Strip/Red Litmus Paper.

Theory
Magnesium is an extremely active metal. Magnesium oxide is formed when it reacts with oxygen.

During this process, two elements, magnesium and oxygen, react to form the compound magnesium oxide. Such reactions are referred to as combination reactions.

Magnesium oxide is basic in nature because it forms magnesium hydroxide when dissolved in water.

Magnesium oxide changes the colour of the red litmus solution to blue.

Result

Magnesium is a silver-white metal.
Mg burns in the air, emitting a bright white flash, and then combines with oxygen to form basic magnesium oxide.
2Mg + O2 → 2MgO
MgO is a basic element.
The experiment shows that burning magnesium ribbon in air is a direct combination reaction.
The formation of magnesium oxide is a chemical change.
