The solubility of Na^SO4 + 10H2O increases with the temperature from 0 to 34°. At 34° and above, it is converted into the anhydrous salt, the solubility of which is least at 103-17°, which is the boiling-point of the saturated solu- tion, and increases by cooling from that temp, down to 18-17°. Below the latter tempera- ture the anhydrous salt cannot e.xist in the presence of H„0, but is converted into Na.,S04-f 7H2O, or Na.2SO4-t-10H2O. The solubility of Na^S04 + 7H20 increases with the temperature from 0-26°, and at 27° it is converted into the anhydrous salt. Thus there are two different rates of solu- bility for Na.^S04 for temperatures from 0-18°, tliree dillercnt rates from 18-26^ two from 26-34°, and only one above 34°. 1.
