Lithium Sulphate Solution: Lithium Carbonate Dissolved in Sulphuric Acid (Thorpe, 1912)

Lithium sulphate is made by dissolving lithium carbonate in sulphuric acid. Made up to 15 g of lithium per litre and neutral, the solution is the feed for precipitating lithium fluoride. Result: one litre of neutral lithium sulphate solution with 15 g of lithium. Source: Thorpe, Dictionary of Applied Chemistry vol. 3 (1912), LITHIUM, p. 339. The amounts are ours, worked out from the reaction. Sulphuric acid is corrosive. Picture drawn by Youblob.
