The solution is tested by litmus paper for acidic nature. The change ... Ash from magnesium ribbon is magnesium oxide.

Solution of Ash of Magnesium Ribbon

Magnesium is a highly reactive metal that easily reacts with oxygen in the air to form magnesium oxide. When magnesium ribbon is burned in air, it undergoes a chemical reaction to produce a powdery white substance known as ash. This ash is actually magnesium oxide, which is a compound formed by the combination of magnesium and oxygen atoms.

Chemical Reaction:
The reaction between magnesium and oxygen can be represented by the following chemical equation:

2Mg + O2 → 2MgO

Here, two atoms of magnesium react with one molecule of oxygen gas to produce two molecules of magnesium oxide.

Formation of Ash:
When a magnesium ribbon is ignited, it starts to burn with a bright white flame. This is due to the intense heat generated during the reaction. As the magnesium ribbon burns, it combines with oxygen from the air to form magnesium oxide. The ash that remains after the reaction is the magnesium oxide compound.

Properties of Magnesium Oxide:
Magnesium oxide (MgO) is a white, odorless, and tasteless solid. It has a high melting point and is insoluble in water. Magnesium oxide is a refractory material, meaning it can withstand high temperatures without melting or decomposing. It is also a basic oxide and exhibits basic properties. When magnesium oxide is dissolved in water, it forms magnesium hydroxide, which is alkaline in nature.

Uses of Magnesium Oxide:
Magnesium oxide has various applications due to its unique properties. Some of its common uses include:

1. Refractory material in the manufacturing of crucibles, furnace linings, and insulation materials.
2. Ingredient in the production of magnesium-based cement and fireproof materials.
3. Supplement in agriculture to provide magnesium and neutralize acidic soils.
4. Component in the production of magnesium alloys, ceramics, and glass.
5. Antacid in medicine to treat heartburn and indigestion.

Overall, the solution of ash of magnesium ribbon is magnesium oxide, which is formed when magnesium reacts with oxygen during combustion. Magnesium oxide has several important applications in various industries and fields.
