Understand the relationship between [H+] and [OH-] in water, which is governed by the ion product of water (Kw). At 25°C, Kw is 1.0 x 10^-14 M^2.
Use the formula Kw = [H+][OH-] to find [H+]. Rearrange the formula to solve for [H+]: [H+] = Kw / [OH-].
Substitute the given [OH-] value into the equation: [H+] = 1.0 x 10^-14 M^2 / 1.0 x 10^-10 M.
Perform the division to calculate [H+]. This involves dividing the ion product of water by the hydroxide ion concentration.
Compare the calculated [H+] with the provided options to identify the correct answer.
