Answer:

The hydroxide ion concentration is 0.003981 M.

The hydronium ion concentration is
2.5119* 10^(-12) M.

Step-by-step explanation:

The pOH of an aqueous solution at 25°C = 2.40


pOH=-\log[OH^-]


2.40=-\log[OH^-]


[OH^-]=0.003981 M

The hydroxide ion concentration is 0.003981 M.

The pH of an aqueous solution at 25°C = ?

The relationship between pH and pOH :

pH + pOH = 14


pH=14- pOh = 14-2.40 =11.6


pH=-\log[H_3O^+]


11.6=-\log[H_3O^+]


[H_3O+]=2.5119* 10^(-12) M

The hydronium ion concentration is
2.5119* 10^(-12) M.
