Ammonium bicarbonate chemical formula

Ammonium bicarbonate chemical formula NH?HCO? Ammonium bicarbonate is a white compound in the form of granular, plate or columnar crystals with an ammonia odor. Ammonium bicarbonate is a carbonate, so it must not be placed with acid, because acid will react with ammonium bicarbonate to generate carbon dioxide, which makes ammonium bicarbonate deteriorate. But rural areas also use ammonium bicarbonate can react with acid this property, ammonium bicarbonate will be placed in the vegetable greenhouse, the greenhouse will be sealed, and the ammonium bicarbonate will be placed in a high place, adding dilute hydrochloric acid. At this time, ammonium bicarbonate will react with hydrochloric acid to produce ammonium chloride, water and carbon dioxide. Carbon dioxide can promote plant photosynthesis and increase vegetable production, and the ammonium chloride generated can be used again as a fertilizer.

Ammonium bicarbonate has ammonium ions in its chemical formula, which is an ammonium salt, and ammonium salts can't be put in a place with alkali ****, so ammonium bicarbonate should never be put together with sodium hydroxide or calcium hydroxide.

Chemical properties

The aqueous solution is alkaline, unstable, decomposed into carbon dioxide, ammonia and water above 36 ℃, 60 ℃ can be decomposed. There is hygroscopicity, decomposition will be accelerated after deliquescence.

The chemical equation of the reaction related to it is:

NH4HCO3+HCl=====NH4Cl+H2O+CO2↑

NH4HCO3==Δ==NH3↑+H2O+CO2↑

H2SO4+NH4HCO3==H2O+CO2↑+NH4HSO4 ( in excess of dilute sulfuric acid)

H2SO4+2NH4HCO3==2H2O+2CO2↑+(NH4)2SO4 (in excess of ammonium bicarbonate)

2NH4HCO3+2NaOH (small amount) = (NH4)2CO3+Na2CO3+2H2O

NH4HCO3+2NaOH (large amount) =Na2CO3+H2O+NH3:H2O

NH4HCO3+2NaOH==Δ==NH3↑+Na2CO3+2H2O
