Why silica and not silicate?

Form silica and silicate pages:


...silicate is a compound containing an anion in which one or more central silicon atoms are surrounded by electronegative ligands.

In the vast majority of silicates, including silicate minerals, the Si atom shows tetrahedral coordination by 4 oxygens. ..(SiO4 form)

Silica, or silicon dioxide, SiO2, is sometimes considered a silicate, although it is a special case with no negative charge and no need for counter-ions. Silica is found in nature as the mineral quartz, and its polymorphs.

...silica is not soulable in water.


If silica is is not soulable in water, why talk about dissolved silica?

Just want to get a grip of the different terms :-)
