Question 42 • Chemistry

The pOH of a solution is 6 point 0 Which statement is correct? Use pOH is equal to negative log times open bracket OH raised to the negative power close bracket and pH plus pOH is equal to 14

Answer
A
The concentration of OH raised to the negative power ions is 1 point 0 times 10 to the negative 8 power cap m .
B
The pH of the solution is 20 point 0 .
C
The pH of the solution is 8 point 0 .
D
The concentration of OH raised to the negative power ions is 1 point 0 times 10 to the 6th power cap m .

Explanation

Use pH + pOH = 14. With pOH = 6.0, pH = 14 − 6.0 = 8.0, so the correct statement is that the pH of the solution is 8.0. The hydroxide concentration is 10⁻⁶ M, not either concentration listed in choices A or B.
