Poh greater than 7
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? WebAt 25 °C, a pH < 7 indicates an acidic solution, a pH > 7 a basic solution, and a pH = 7 a neutral solution. Key Equations pH = −log[H3O+] pH = − log [ H 3 O +] pOH =−log[OH−] pOH = − log [ OH −] [H3O+]= 10−pH [ H 3 O +] = 10 − …
