WebpH = – log [OH –] At pOH 7, the solution is neutral. If the pOH value is less than 7, a solution will be alkaline, while a solution will be acidic if the pOH value is more than 7. We can use numerous parameters to determine the pOH value. pOH from Molarity; pOH from pH; pOH from pKb; pOH from Molarity 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. t shirts stitching design
