silicic acid

n.
Hydrated silica, SiO2·nH2O, produced by acidification of sodium silicate solution. Depending on the proportion of water, it may have any consistency from jelly to amorphous solid.

silicic acid

n
(Elements & Compounds) a white gelatinous substance obtained by adding an acid to a solution of sodium silicate. It has an ill-defined composition and is best regarded as hydrated silica, SiO2.nH2O
