The correct answer is A. Acidic. The solution obtained from the ash of magnesium ribbon is acidic. When magnesium reacts with oxygen, it forms magnesium oxide (MgO). When MgO dissolves in water, it undergoes hydrolysis to produce magnesium hydroxide (Mg(OH)2), which is a weak base. However, the reaction between magnesium hydroxide and carbon dioxide in the air results in the formation of magnesium carbonate (MgCO3), which is slightly soluble in water. The dissolution of magnesium carbonate in water leads to the formation of magnesium ions (Mg2+) and carbonate ions (CO32-). The presence of carbonate ions results in the formation of carbonic acid (H2CO3) through a reversible reaction. Therefore, the solution obtained from the ash of magnesium ribbon is slightly acidic due to the presence of carbonic acid.

Understanding Magnesium Ribbon Ash
When magnesium ribbon is burned in air, it reacts with oxygen to form magnesium oxide. This ash is primarily composed of magnesium oxide (MgO).
Properties of Magnesium Oxide
- Basic Nature: Magnesium oxide is a basic oxide. When it dissolves in water, it reacts to form magnesium hydroxide, which is a strong base.
- pH Level: A solution of magnesium hydroxide has a pH greater than 7, indicating its basic nature.
Reaction with Acids
- Neutralization: Magnesium oxide readily reacts with acids to form salts and water. This property is characteristic of basic substances.
- Acidic Solutions: When magnesium oxide interacts with acids, it neutralizes them, confirming its basic behavior.
Conclusion
Therefore, the ash produced from burning magnesium ribbon is not acidic; rather, it is basic in nature. This explains why option 'A' is the correct answer, as the solution of ash from magnesium ribbon is basic due to the inherent properties of magnesium oxide formed during combustion.
