Question

The solution of ash of magnesium ribbon is acidic , basic or neutral?

Answer 1

Hint: The compound obtained at the end of the burning, that is the ash, is magnesium oxide ( \[MgO\] ). Thus, the nature of the compound, magnesium oxide, is decided on what type of oxide is the compound magnesium oxide ( \[MgO\] ).

Complete answer:
The solution of ash of magnesium ribbon is basic, this is due to the compound of what the ash of magnesium ribbon is made up of. The ash of magnesium ribbon is made up of magnesium oxide, and thus the ash is basic in nature.
An oxide is a compound in which oxygen reacts with different elements and then the nature of the compound will be decided.
There are mainly four types of oxides in nature, one which has acidic nature, another which has basic nature, another one which has neutral nature and last one which shows both acidic and basic nature according to the situation.
The oxides of non-metals are considered as acidic oxides because they show acidic nature, similarly the oxides of metals are basic oxides as they show basic nature.
Therefore, the ash of magnesium ribbon is basic and not acidic or neutral.

Note:
The nature of oxides are decided by their nature when subjected to reaction with water. Depending on their reaction with water, their nature is decided whether they will be acidic, basic or neutral. Examples of acidic oxides are chlorine oxides, vanadium oxides etc. Examples of basic oxides are carbon oxides, calcium oxides, magnesium oxide, etc. Examples of neutral oxides are carbon monoxide, nitrogen oxides, etc.
