Aqueous
Ammonia is produced by dissolving anhydrous ammonia in
water . By passing
ammonia in water following reaction takes place: NH3(aq)+H2O(l)
NH4+(aq)+OH(aq)
and its chemical formula is NH4OH. The strength of aqueous
ammonia depends on percentage of anhydrous ammonia
passed in given water. The strength of an aqueous ammonia
solution can be measured in: Percentage (%), Percentage weight/volume
(% w/v), Percentage weight/weight of solution (% w/w), Percentage
weight/weight of solution(%g/g) and Specific Gravity(S.G).
Specific gravity of aqueous ammonia varies depending on
temperature of solution. Specific gravity is measured by
Hydrometer and Baumé scale is a pair of hydrometer
scales (also noted by degrees Baume, degrees Baumé;
B°, Be°, Bé°, Baume). Hydrometer scale
shows ratio of the density of the liquid to the density
of water.Aqueous Ammonia also known as ammonia water, ammonia solution,
aqua ammonia, ammonium hydroxide, diluted ammonia and in
India it is commonly known as liquor ammonia.Aqueous Ammonia is a colorless liquid with a pungent odor,
inheriting water colour and ammonia property. It is an
excellent acid neutralizer and its pH varies with concentration.
Verma Gases (India) Pvt. Ltd. Ankleshwar Gujarat has the
largest manufacturing capacity for aqueous ammonia per
day in India.
