Potassium feldspars are common members of the alkali feldspar group and form a complete solid solution series from KAaSi3O8 through (K, Na)AlSi3O8 to NaAlSi3O8. You really need more information for a precise chemical composition as K-Feldspars can have a wide range of chemical compositions.
Granite contains plagioclase feldspar and potassium feldspar. It really depends on the composition of the magma from which it forms. If the granite has a lot of pink in it, chances are it is potassium feldspar (K-Spar). If it is dominated by white, then the feldspar is probably plag.
Pink granite would consist primarily of potassium feldspar and quartz with minor amounts of mica and other feldspars.

Potassium (potash) feldspars is KALSi3O8
The chemical composition of Feldspars are KAlSi3O8 â?? NaAlSi3O8 â?? CaAl2Si2O8. They are rock forming minerals that make up %60 of the Earth's crust.
1 atom of Potassium, 1 of Chlorine and 3 of Oxygen
Feldspars break down to form clays like kaolin.
Granite is a rock containing both amphibole and potassium feldspar.
potassium is silvery white, its chemical composition is brighter than light! How's that???
Yes, Granite is composed mainly of quartz and potassium feldspar

Mineral composition of granite: K-feldspar Na-feldspar Quartz Muscovite Biotite
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.
potassiun feldspar, quartz, plagioclase feldspar,biotite, and amphibole.
Potassium feldspar and plagioclase feldspar are used for ceramics, glass, enamel, soap, false teeth, and scouring powders.
Feldspar is not a specific substance, but a class of aluminosilicates of potassium, sodium and calcium.
feldspar and quartz
It depends on the type of feldspar. Potassium Feldspar (also called K-Spar), contains potassium, aluminum, silicate: KAlSi3O8. Plagioclase Feldspar, on the other hand, contains calcium or sodium, aluminum, and silicate: NaAlSi3O8 or CaAl2Si2O8.
