![[\text{H}^{+}] = 10^{-\text{pH}}](/tpl/images/0015/8660/d14eb.png)
, where ![[\text{H}^{+}]](/tpl/images/0015/8660/3f662.png)
is the concentration of proton in the solution.
.![[\text{H}^{+}] \cdot [\text{OH}^{-}] = \text{K}_w](/tpl/images/0015/8660/76721.png)
, where ![[\text{OH}^{-}]](/tpl/images/0015/8660/3da65.png)
the concentration of hydroxide ions and 
is the dissociation constant of water.
at 0.10 MPa and 25 °C. As a result, ![[\text{OH}^{-}] = \text{K}_w / [\text{H}^{+}] = 10^{14} / (6.31 \times 10^{-7}) = 1.6 \times 10^{-8} \; \text{mol}\cdot \text{dm}^{-3}](/tpl/images/0015/8660/0d14c.png)

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
