WebThe pOH scale is essentially the pH scale, but backwards. This is shown in the following image: On the pOH scale, all bases are below 7. A strong base would be between 1 and 3, while a weak base would be between 4 and 6. 7 is still neutral and above 7 is an acid. A weak acid would be between 8 and 10 and a strong acid would be between 11 and 14. cultural differences between us and koreaWebThis video demonstrates how to calculate pH, pOH, [H3O+] and [OH-] in acids and bases chemistry.In this video we take a look at the formulas and equations of... east laytonWebMar 28, 2024 · What is the pH of these solutions? pOH = 5.55 [ H 3 O +] = 10 –11 M [ O H −] = 10 –8 M Solution From Equation 15.8. 3, pH + pOH = 14.00.
