Characters. - In colourless transparent prisms.
Solubility. - It is soluble in water.
Reactions. - The solution in water is alkaline, giving white precipitates with chloride of barium, chloride of calcium, and sulphate of zinc, and a brick-red precipitate with nitrate of silver (arseniate), all of which are soluble in nitric acid.
Dose.- 1/16 to 1/8 gr.; of the dried salt, 1/24 to 1/12 gr.
Preparations. b. and u.s.p.
liquor Sodii Arseniatis. 4 1/2 grains dried in 1 fl. oz. of water, or 1 in 100. B. and U.S.P.
Dose. - 5 to 10 minims.
Action. - It acts like other preparations of arsenic, but does not irritate the stomach so much, and may be given in larger doses. In frogs it produces, like arsenious acid, paralysis of the brain and spinal cord, but is much less powerful (Ringer and Murrell).
Uses. - It may be used in the same diseases as arsenious acid. It is perhaps one of the best remedies for neuralgia which we have.
