Radium Silicate RaSiO3

Radium salts are apparently adsorbed by gelatinous silica. It is possible that the silicate may be formed. The acidity of the solution plays an important part, since acid exerts a desorbent action, the process possibly being represented by the equation,

RaSiO3 + 2HCl = RaCl2 + H2SiO3.
