which of these correctly defines the poh of a solution?\n the log of the hydronium ion concentration\n the negative log of the hydronium ion concentration\n the log of the hydroxide ion concentration\n the negative log of the hydroxide ion concentration

which of these correctly defines the poh of a solution?\n the log of the hydronium ion concentration\n the negative log of the hydronium ion concentration\n the log of the hydroxide ion concentration\n the negative log of the hydroxide ion concentration

Answer

Brief Explanations:

The pOH of a solution is defined as the negative - logarithm of the hydroxide ion concentration. Mathematically, $pOH=-\log[OH^-]$. The first two options pertain to hydronium ion concentration which is related to pH ($pH = -\log[H_3O^+]$), and the third option is an incorrect definition as it lacks the negative sign.

Answer:

the negative log of the hydroxide ion concentration
