Millon’s Reagent

Millon s reagent Dissolve one part of mercury in two parts of nitric acid (d. 142) first in the cold and then by warming. Dilute the solution with two volumes of water. 

Millon s reagent is prepared by dissolving 1 part of mercury in 1 part of nitric acid (D 1 -41) first in the cold and afterwards at a gentle heat the solution obtained is diluted with twice its volume of water and allowed to settle, the clear liquid being decanted off. 

B. Add a few drops of Millon s Reagent to a 1 100 aqueous solution. A white, curdy precipitate forms. 

Millon s Reagent To 2 mL of mercury in an Erlenmeyer flask add 20 mL of nitric acid. Shake the flask in a hood to break the mercury into small globules. After about 10 min add 35 mL of water, and if a precipitate or crystals appear, add sufficient 1 5 nitric acid (prepared from nitric acid from which the oxides have been removed by blowing air through it until it is colorless) to dissolve the separated solid. Add a 1 10 solution of sodium hydroxide, drop wise, with thorough...

Millon s reagent. Place 20 g of mercury in a beaker under a well-ventilated hood. Add 30 ml of concentrated nitric acid. When the reaction is complete, add 65 ml of water. It is best to make the solution in small amounts. 

Millon s reagent. Solution produced by dissolving mercury in equal weight of nitric acid (d 1.41), and solution diluted to twice the volume and decanted from the precipitate. 

To prepare Millon s reagent, dissolve mercury in an equal weight of nitric acid (1-4 sp gr) and dilute the solution to twice its volume with cold water.)... 

Millon s reagent (for albumins and phenols). Dissolve 1 part of mercury in 1 part of cold fuming nitric acid. Dilute with twice the volume of water and decant the clear solution after several hours.
