WebNov 8, 2009 · A silicate is a salt of silicic acids and one or several metals. Orthosilicic acid, H 4 SiO 4, is just the simplest form, other silicic acids are made of several linked SiO 4 units with attached hydrogen. One could think that silicates form when a metal hydroxide and orthosilicic acid react, like H 4 SiO 4 + 2 Mg(OH) 2 → 2 H 2 O + Mg 2 SiO 4 [11] http://quartzpage.de/gen_chem.html
