Sample of pure water has a hydronium concentration of 1.0 × 10-7 m. what is the ph of the water?

The pH of the water is 7.

Explanation:

The pH of the solution is defined as negative logarithm of H^+ or hydronium ions ions in the solution.

pH=-\log[H^+]

So, H^+ concentration of water = 1.0\times 10^{-7} m

pH=-\log[1.0\times 10^{-7}]=7

The pH of the water is 7.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
