Question: is nh4hco3 acid or basic?
Answer: 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.
