Beryllium Chromate, BeCrO4.H2O

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.
