Note 87 — Chapter III · Concluding the Route to the Great Salt Lake City.

According to Dr. L. D. Gale (Appendix F. to Captain Stansbury’s “Expedition to the Great Salt Lake”), who tested specimens of this saleratus, “it is composed of the sesquicarbonate of soda, mixed with the sulphate of soda and chloride of soda, and is one of the native salts called Trona, found in the Northern Lakes, in Hungary, Africa, and other countries.”

“Three grammes of this salt in dry powder, cleared of its earthy impurities, gave carbonic acid 0·9030 of a gramme, which would indicate 1·73239 grammes of the sesquicarbonate. The other salts were found to be the muriate and sulphate of soda: the proportions were not determined.”
