Silicic acid: The omniscient molecule
Science of The Total Environment, 2019We contend that silicic acid is a much under-valued molecule and specifically in the context of its role in establishing and maintaining life on Earth. Silicic acid can also be an ill-understood molecule with its chemistry all too often confused with that of either silicates or silica.

Interaction of Ascorbic Acid with Silicic Acid
Journal of Pharmaceutical Sciences, 1970Interaction of ascorbic acid with silicic acid in the solid state was studied using diffuse reflectance spectroscopic techniques. Surface degradation products from ascorbic acid breakdown were effectively observed using diffuse reflectance spectroscopy, whereas the corresponding transmittance spectral method did not give significant information ...

Preparation of transfer ribonucleic acid with silicic acid
Archives of Biochemistry and Biophysics, 1972Abstract A modification of the nondenaturing procedure of Sueoka and Hardy (1) for the isolation of transfer ribonucleic acid is described. This procedure has been used for the large scale isolation of transfer-RNA from extracts of Escherichia coli and involves a batch treatment with silicic acid, DEAE-cellulose column chromatography, and an ...

1. The solubilities of silicic acid gels in water at 25.9° and 97° were studied. 2. It was shown that the silicic acid that passed into solution was present entirely in, the form of simple molecules and ions capable of reacting with molybdic acid.

Interaction of silicic acid with goethite
Journal of Colloid and Interface Science, 2007The adsorption of Si on goethite (alpha-FeOOH) has been studied in batch experiments that cover the natural range of Si concentrations as found in the environment. The results have been interpreted and quantified with the charge distribution (CD) and multi-site surface complexation (MUSIC) model in combination with an extended Stern (ES) layer model ...

Different types of crystalline silicic acids are obtained from layer silicates by proton exchange. Hydrated alkali layer silicates formed from SiO2 dispersions in alkaline solutions at 100–150°C are precursors of several acids which are thus available in large amounts.
