A Text Book of Inorganic Chemistry
There are two silicic acids: Orthosilicic acid, H4SiO4 or Si(OH)4 Metasilicic acid,
H2SiO3 or SiO(OH)2 Orthosilicic acid is obtained as a gelatinous precipitate by.
leading silicon tetrafluoride into water. The precipitate is washed with water, then

Modern Inorganic Chemistry
Metasilicic acid is obtained as a gelatinous ppt. by adding HCl to a concentrated
solution of an alkali silicate like Na2SiO3. Na2SiO3 + 2HCl 2NaCl + H2SiO3
Gelatinous ppt. The gelationous ppt. of H2SiO3 so formed is filtered, dehydrated

Unit Processes in Drinking Water Treatment
Metasilicic acid is a weak divalent acid of which the acidity constants are the
following: [H2Si03] tH*l[SiO32- [HSiCV] c: = 10 Any acid stronger than metasilicic
acid can displace the latter compound from the metasilicate and induce meta- or
...

Cortisone, hydrocortisone, DOCA or water melon feeding markedly increased
metasilicic acid excretion. In the Yokohama area, where the metasilicic acid
content of drinking water is 30.23 mg./l., the incidence of hypertension was 19.34
%, ...
If two molecules of metasilicic acid dimerize, as shown in Figure 5.2A, there is a
substantially smaller kinetic barrier for this process. Because H2SiO3 is
electroneutral (the isoelectric point of bulk silica ranges from 2 to 4) compared to
...

The constitution of the silicates
In the first place, metasilicic acid itself is defectively known, and no ether of the
form R2Si03 has yet been certainly obtained. Troost and Hautfeuille's ether (
C2H5)8Si4012 suggests the possibility that metasilicic acid, like metapbosphoric
acid, ...
