Poh greater than 7
WebThe concentration of hydroxide ion in a solution of a base in water is greater than 1.0 × 10 −7M at 25 °C. The concentration of H3O+ H 3 O + in a solution can be expressed as the pH of the solution; pH = −log [H3O+] pH = − log [H 3 O +]. The concentration of OH − can be expressed as the pOH of the solution: pOH = −log [OH − ]. WebpOH = −log [ OH −] = −log ( 1.0 × 1 0 −7) = 7.00 And so, at this temperature, acidic solutions are those with hydronium ion molarities greater than 1.0 × 10 −7 M and hydroxide ion …

WebAug 29, 2024 · The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH. What is pOH range?
