Answer:

Never

Explanation:

The OH⁻ ion in a sample of water comes from the process of autoionization of water. That is, water reacts with itself to give the hydronium ion (H₃O+) and hydroxide ion (OH⁻). The reaction for this process is H₂O + H₂O ⇄ H³O⁺ + OH⁻. As long as there are at least two molecules of water, the process will occur giving hydroxide ions.

[tex]OH^{-}[/tex] ion is also referred to as Hydroxide ion.

  • In water, we have both the [tex]OH^{-}[/tex] ion and the [tex]H^{+}[/tex] (hydrogen) ion.

This correct option is option D because there is never a condition where the  [tex]OH^{-}[/tex] ion concentration in water is expected to be zero.

  • This is because the reaction to produce water is given as:

[tex]H^{+} + OH^{-} = H_{2} O[/tex]

As long as this reaction keeps on happening, the concentration of [tex]OH^{-}[/tex] in the water will never be zero.

Therefore, the correct option is D.
