Oxide of cobalt in very small quantities yields, with silicic acid, an intensely blue silicate.
This well-known substance is essentially a mixture of silicates with an excess of silica or silicic acid.
I knew that silicic acid, practically glass, was represented by sea-sand.
The minerals augite and hornblende are double salts of silicic acid, magnesium, and calcium with some ferrous oxide.
This method is particularly effective in the preparation of silicic acid.
The hydrate of baryta combines with the silicic acid, and forms the super-basic silicate of baryta, while the oxides become free.
Stannic acid has a greater tendency to form a base than has silicic acid.
Pour the silicic acid solution into a large porcelain basin.
At the commencement of this article, it was stated that silicic acid, or silica, could be made soluble in water.
The silicic acid will fuse into a bead, which becomes clear when it is cold.
