The advantage of barium over lime as a precipitant is the more ready crystallisability of the citric acid from the solution thus obtained.
The researches of Pelletier and Caventou tend to show that the solution of tin used as a precipitant should be at the maximum of oxidation or chlorination, to produce the richest shades of carmine.
This method has the advantage of the water being perfectly freed from any excess of the precipitant by heat.
