The rare earth elements can then be extracted from the waterleached residue by selectively leaching the oxysulphide phase with 3.5 wt.% hydrochloric acid. In comparison with the currently used sodium hydroxide process, the reaction with sodium carbonate simplifies the separation of the rare earth ...
The carbonate ion (CO2−3) can undergo hydrolysis in water. Hydrolysis is a reaction with water that leads to the formation of a weak acid and a strong base. The carbonate ion reacts with water to produce bicarbonate (HCO−3) and hydroxide ions (OH−):...
Heating the sodium sulfate with coal and limestone produced a “black ash” that contained sodium carbonate, calcium sulfide, unreacted coal, and calcium carbonate. Sodium carbonate was separated from the black ash by leaching with water. The overall reaction is as follows: Na2SO4 + 2C + ...

The crystals are again dissolved in water, the sodium bicarbonate is then precipitated with carbon dioxide, and filtered. The...
Sodium - Chemical Properties, Reactions, Uses: Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). Its chemistry is well explored. Sodium is ordinarily quite reactive with
The anhydrous reaction of sodium carbonate & phosphorus pentoxide, initiated by local heating, can generate relatively high temp.DECOMP BY ACIDS WITH EFFERVESCENCE; COMBINES WITH WATER WITH EVOLUTION OF HEATWhen sodium carbonate was applied to red hot aluminum, an explosion occurred.Stratified concentrate...
