Potassium Carbonate K2CO

According to J. J. Pohl, potassium sesquihydrated carbonate loses S-59 per cent, of water at 100°, and forms monohydrated potassium carbonate, K2CO,.HaO, which at 130°-135°... 

Sodium chloride (NaCl) is the most common sodium salt. — it is the chemical that makes ocean water salty. Plants growing in the ocean take up so much of the sodium that people along the seacoasts of the world used to burn dried seaweed to secure soda ash (sodium carbonate, Na,CO,). Inland plants, on the other hand, pick up potassium from the soil. Inland people boiled out wood ashes in large pots to get potash (potassium carbonate, K2COs). 

The solutions used were Potassium Carbonate saturated at 15° (contained 57.2 grams K2CO, per 100 cc.). Aqueous Ammonia of 0.885 Sp. Gr. (contained about 33 per cent ammonia). The determinations were made by adding successive small quantities of one of the solutions to a measured volume of the other, and observing the point at which opalescence appeared.

O. L. Erdmann reported potassium cobaltous tetranitrite, K2Co(N02)4, or 6K0H.3Co3(N02)2, to be separated as a yellow crystalline powder when soln. of cobaltous chloride and an excess of potassium nitrite are mixed. No oxygen is absorbed from the air during its formation, and O. L. Erdmann, and S. P. Sadtler used an atm. of carbon dioxide. The salt was also prepared by A. Stromeyer, and C. D. Braun. The salt is insoluble in cold water, but soluble in hot water, forming a red soln. It forms a violet soln. if potassium acetate is present, containing cobaltous salts. The salt decomposes when heated. C. D. Braun said that cobaltic hydroxide is precipitated when the soln. is boiled with potash-lye. 0. L. Erdmann said that the cobalt is not contained in the salts as a base in the...
