Report on the Chemical Examination of several specimens of 

 Salt from the Loonar Lake in the Deccan, by J". E. Mayer, 

 Professor of Chemistry, Madras. 



Qualitative Examination of Salt No. 1 " Dulla." 



A portion, not weighed, treated by dilute sulphuric acid gave off 

 a very large quantity of carbonic acid, leaving a notable portion of 

 impurities undissolved, consisting of dirt, earth and some organic 

 matters ; these were separated by nitration. A portion of the fil- 

 trate ascertained to be acid, was then treated by solution of nitrate 

 of silver, a copious white precipitate was deposited, showing the 

 presence of chlorine. A second portion of the filtered solution 

 was neutralized by solution of ammonia, iron and alumina were 

 thrown down in small quantity : the precipitate was separated by 

 filtration ; to the filtrate, solution' of oxalate of ammonia was add- 

 ed, white precipitate took place ; this was separated by filtration, 

 and to the filtered solution, phosphate of soda was added, a small 

 crystalline precipitate occurred. 



A fresh portion of salt taken and tested by the blow pipe for 

 the presence of soda, gave the characteristic flame ; the only base 

 that could be left being potash, it was passed over (as if present it 

 could only be in small quantity) till the quantitative examination 

 was carried out.
