White precipitateof mg(oh)2 attains blue colour when precipitate in the presence of magneson reagent is and adsorption or absorption
Answers
Answer:
Explanation:
Magneton reagent definition:
The Magneton reagent is a test that finds out whether there is magnesium in a solution. It is an azo dye that is used as a spot test reagent that reacts with Mg(OH)2 in a basic solution to form a blue lake.
Definition of adsorption:
Adsorption is a phenomena of gases or solutes adhering to solid or liquid surfaces, and it is a mass transfer process. The reason for adsorption on a solid surface is that uneven forces cause molecules or atoms to retain some of their surface energy.
Definition of absorption:
The molecules, atoms, and ions of the substance being absorbed enter the bulk phase (gas, liquid, or solid) of the medium in which it is taken up. Absorption is a chemical or physical phenomena. The process of anything becoming totally absorbed into another substance is known as absorption.
When precipitated in the presence of the magneton reagent, the Mg (OH)2 precipitate turns blue (dye) The bluish tinge results from adsorption.
