The polymeric forms of silicic acid in various silicate antacids were studied by the trimethylsilyation and silicomolybdate methods. Composition and distribution were markedly influenced by the kind of silicates. The low molecular weight silicic acids determined by the silicomolybdate method were estimated to include silicic acid molecules such as H_4SiO_4,H_6Si_2O_7,H_8Si_3O_<10>, H_3Si_4O_<12>, and some linear polymer, and the forms of colloidal silicic acids were estimated to have H_<2n+4>Si_<2n>O_<5n+2>. The trimethylsilylation method is excellent for the silicate structure analysis. It is possible to learn of a measure of the gastrointestinal absorption of silicic acid by the silicomolybdate method.
