Sodium carbonate is a white, odorless powder or granule at room temperature. It has water absorption, and gradually absorbs 1mol/L of water (about = 15%) in exposed air. Its hydrates are Na2CO3 · H2O, Na2CO3 · 7H2O and Na2CO3 · 10H2O. Solubility Sodium carbonate is easily soluble in water and glycerin. At 20 ° C, 20 grams of sodium carbonate can be dissolved per 100 grams of water, and the maximum solubility is at 35.4 ° C. 49.7 grams of sodium carbonate can be dissolved in 100 grams of water. The solution is alkaline and can make phenolphthalein red.
