Reactions
It dissolves in water to give a mildly alkaline solution. It is insoluble in acetone and alcohols.
Ammonium bicarbonate decomposes above about 36 °C into ammonia, carbon dioxide, and water in an endothermic process and so causes a drop in the temperature of the water:
- NH4HCO3 → NH3 + H2O + CO2.
When treated with acids, carbon dioxide is also produced:
- NH4HCO3 + HCl → NH4Cl + CO2 + H2O.
Reaction with base produces ammonia.
It reacts with sulfates of alkaline-earth metals to precipitating their carbonates:
- CaSO4 + 2 NH4HCO3 → CaCO3 + (NH4)2SO4 + CO2 + H2O.
It also reacts with alkali metal halides, giving alkali metal bicarbonate and ammonium halide:
- NH4HCO3 + NaCl → NH4Cl + NaHCO3;
- NH4HCO3 + KI → NH4I + KHCO3;
- NH4HCO3 + NaBr → NH4Br + NaHCO3.

Famous quotes containing the word reactions:
“Prolonged, indiscriminate reviewing of books is a quite exceptionally thankless, irritating and exhausting job. It not only involves praising trash but constantly inventing reactions towards books about which one has no spontaneous feeling whatever.”
—George Orwell (1903–1950)
“We have all had the experience of finding that our reactions and perhaps even our deeds have denied beliefs we thought were ours.”
—James Baldwin (1924–1987)
“Separation anxiety is normal part of development, but individual reactions are partly explained by experience, that is, by how frequently children have been left in the care of others.... A mother who is never apart from her young child may be saying to him or her subliminally: “You are only safe when I’m with you.””
—Cathy Rindner Tempelsman (20th century)
