Which equation correctly shows how you could calculate [OH–] from [H+]?

StartBracket upper O upper H superscript minus EndBracket equals StartFraction 1.0 times 10 to the negative 14 power over StartBracket upper H superscript plus EndBracket EndFraction.

The first equation:

[OH–] = (1.0 × 10^−14) / [H+]

Reason: Kw = [H+][OH–] = 1.0×10^−14 (at 25 °C). Solve for [OH–] by dividing both sides by [H+].
