What remained was a pure solution of silicic acid, which could be boiled in a flask, and considerably concentrated, without change.
It is not only on the basic substances upon which it acts, but also on the phosphoric and silicic acids, which it sets free.
Graham considered "colloidal silicic acid a liquid miscible with water in all proportions.
Silicic acid shows some slight tendency to ionize also as a base (see Chapter X) and the basic form of ionization would be favored by the presence of a strong acid (Chapter X).
In the case of silicic acid, which is the next hydroxide one meets as one goes toward the acid end of the series, the conditions are reversed.
By the simplest experiment, any one may satisfy himself that rain-water filtered through field or garden soil does not dissolve out a trace of potash, silicic acid, ammonia, or phosphoric acid.
If rain or other water holding in solution ammonia, potash, and phosphoric and silicic acids, be brought in contact with soil, these substances disappear almost immediately from the solution; the soil withdraws them from the water.
