Abstract

Mixing lead arsenate with lime sulfur results in:

1. A decrease of sulfur in solution.

2. A decrease of calcium in solution.

3. Increase of thiosulfate in solution.

4. Increase of thiosulfate in the residue.

5. Increase of sulfite in solution.

6. Formation of lead sulfide.

7. Formation of a compound containing arsenic and sulfur but insoluable in the lime-sulfur solution,—probably lead thioarsenate.
