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.
