| Beryllium Chromate, BeCrO4.H2O, and the basic compound, BeCrO4.6Be(OH)2, have been described by Glassmann, whose results, however, have not been confirmed by subsequent workers. It appears to be established that a solution of chromic acid absorbs beryllium hydroxide in the exact ratio of 1Be(OH)2:1CrO3, which points to the formation of the neutral chromate. When solutions of beryllium salts are treated with equivalent quantities of chromates, the precipitates at first formed redissolve; but if the chromate is added in excess, yellow precipitates of strongly basic beryllium chromates of uncertain composition are obtained. |
