Name the product formed on burning magnesium and sulphur in air? Write chemical equation of both. Which product is acidic in nature?

Question

Answer

When we burn magnesium in air magnesium oxide is formed.
2mg +o2=2mgo
when we burn sulphur we get sulphur dioxide.
s+o2=so2
sulphur dioxide is acidic in nature..

Answer

Product formed on burning magnesium and sulphur in air:

- When magnesium is burned in air, it forms magnesium oxide (MgO).
- The chemical equation for the reaction is: 2Mg + O2 → 2MgO

- When sulfur is burned in air, it forms sulfur dioxide (SO2).
- The chemical equation for the reaction is: S + O2 → SO2

Acidic nature of the products:

- Among the products formed, sulfur dioxide (SO2) is acidic in nature.
- When sulfur dioxide dissolves in water, it forms sulfurous acid (H2SO3).
- Sulfurous acid is a weak acid that can react with water to release hydrogen ions (H+).
- The presence of hydrogen ions makes the solution acidic, giving it a sour taste and the ability to turn blue litmus paper red.

- On the other hand, magnesium oxide (MgO) is a basic oxide and when it reacts with water, it forms magnesium hydroxide (Mg(OH)2), which is a base.
- The basic nature of magnesium oxide can be seen in its ability to neutralize acids and turn red litmus paper blue.

In conclusion, sulfur dioxide formed on burning sulfur in air is acidic in nature due to the formation of sulfurous acid upon dissolution in water. Magnesium oxide formed on burning magnesium in air, on the other hand, is basic in nature.
