Description:
Sodium carbonate (Na2CO3), also called as soda. It exhibits as a white powder at ordinary circumstances and is a strong electrolyte. It has a density of 2.532g/cm3 and melting point of 851 °C. It is easily soluble in water with general property of salt.
It is a weak acid salt and slightly soluble in ethanol but insoluble in alcohol. Upon being soluble in water, it will be subject to hydrolysis reaction, and making the solution be alkaline with certain corrosiveness and can have neutralization reaction with the acid to form the corresponding salts and release carbon dioxide.
It can subject to decomposition at high temperatures to produce sodium oxide and carbon dioxide. Long-term exposure to air can absorb moisture and carbon dioxide from the air to produce sodium bicarbonate, and form lumps. It has a very strong hygroscopic property and is easy to form lumps without decomposing at high temperatures.
