Σελίδα 83 - Phosphorous acid. Pour into a test tube about 0.5 cc. of phosphorus trichloride (hood) and add a little water, a drop at a time. What gas is evolved (R) ? Finally, add about 5 cc. of water, pour the liquid into an evaporatingdish, and evaporate to a sirupy mass. Dilute this with a little water, transfer the solution to a test tube, and add a few drops of a solution of silver nitrate. Boil the resulting mixture. A black precipitate forms. Explain.
