At temperatures from 80–100 °C (176–212 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. The conversion is faster at 200 °C (392 °F): [80] 2 NaHCO 3 → Na 2 CO 3 + H 2 O + CO 2. Most bicarbonates undergo this dehydration reaction.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
Aluminium carbonate (Al 2 (CO 3) 3), is a carbonate of aluminium.It is not well characterized; one authority says that simple carbonates of aluminium are not known. [2] However related compounds are known, such as the basic sodium aluminium carbonate mineral dawsonite (NaAlCO 3 (OH) 2) and hydrated basic aluminium carbonate minerals scarbroite (Al 5 (CO 3)(OH) 13 •5(H 2 O)) and ...
Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2 O) 6 ]Cl 3 , containing six water molecules of hydration .
