Strong solution of ammonium acetate

Strong solution of ammonium acetate

Aim: Preparation and Evaluation of Strong solution of ammonium acetate

Glassware’s: Beaker, glass rod, & wide mouth amber coloured bottle

Formula:

IngredientsQty givenActivity
Glacial acetic acid453 gIn situ ammonium acetate formation.
Ammonium bicarbonate470 g
Ammonium solution strong100 ml or q.sNeutralizing agent
Purified Waterq.s to 1000 ml 

Procedure:

Glacial acetic acid, ammonium bicarbonate was mixed in 350 ml of purified water.

Strong ammonia solution was added to the above solution until a drop of resulting solution when added to10 drops of water and one drop of bromothymol blue gave a full blue colour and one drop tested with to10 drops of water and one drop of thymol blue gave a full yellow colour.

The solution was diluted with water to make up the volume.

The solution was filled in a lead-free glass container.

Theory:

Ammonium acetate is prepared in situ by a chemical reaction.

NH4 H CO3 +CH3 COOH                   CH3 COONH4   + CO2   +    H2O

Excess acid is added which is not completely neutralized, dilute solutions are used to give a faster reaction to obtain the solution of desired strength. Ammonia is added to obtain a condition of complete neutralization. (pH 7 to 8).

Category: Mild expectorant, diaphoretic and diuretic Dose: 1 to 5 ml.

Storage: Store in a cool, dry place.

Labelling direction: Ammonium acetate 55 to 60 % W/V
