Question

Which is more basic in nature, magnesium or aluminium?

Answer 1

Magnesium is the more basic than Aluminium. Because Aluminium is amphoteric in nature. It has reactions as both a base and an acid . compare Sodium Magnesium is less basic. But compare the Aluminium, Magnesium is more basic.Magnesium oxide is react with water it will give Magnesium hydroxide.

​Aluminium react with base as well as acid,

That aluminium oxide will react with hot dilute hydrochloric acid to give aluminium chloride solution.

In this (and similar reactions with other acids), aluminium oxide is showing the basic side of its amphoteric nature.

With hot, concentrated sodium hydroxide solution, aluminium oxide reacts to give a colourless solution of sodium tetrahydroxoaluminate.

This reaction shows the Aluminium has acidic in nature.
Therefore Magnesium has more basic than Aluminium. That is Magnesium has more basic in nature compared to Aluminium.
