MAGNESON I AR Sensitivity detects 1 ppm Mg
Magneson reagent - The Magneson reagent is a test that determines the presence of magnesium in a solution. It's an azo dye that's used as a spot test reagent and produces a blue lake when reacted with $ Mg{(OH)_2} $ in a basic solution.Take 1-2 drops of test solution in a spot plate and add 2-3 drops of magneson I reagent (4-(4-Nitrophenylazo)-resorcinol) and add 1 drop of 2M sodium hydroxide NaOH to make it alkaline. Blue colouration or blue precipitate is formed depending on the concentration of magnesium.
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.
