Excerpt from Chemical, Physical, and Insecticidal Properties of ArsenicalsIt is not known who made the first sample of calcium arsenate. Pickering (31) in 1907 stated that calcium arsenate had already been used in the United States as an insecticide. He gave the proportions of a calcium salt and an arsenate to be united in preparing calcium arsenate, recommending the use of an excess of lime in order to pro duce a calcium arsenate with all the arsenic precipitated and there fore containing no appreciable amount of water-soluble arsenic.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
