The pOH of a solution is 6. 0. Which statement is correct? Use p O H equals negative logarithm StartBracket upper O upper H superscript minus EndBracket. And p H plus P O H equals 14. The pH of the solution is 20. 0. The concentration of OH– ions is 1. 0 times 10 to the negative 8 moles per liter. The concentration of OH– ions is 1. 0 times 10 to the 6 moles per liter. The pH of the solution is 8. 0.
