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 WebFeb 1, 2015 · If you're not dealing with a buffer, then you must use the acid dissociation constant, Ka, to help you determine the pH of the solution. In this case, you need to determine [H +] in order to determine pH, since. pH = −log([H +]) The value of the acid dissociation constant can be derived from pKa. Ka = 10-pKa. For a strong acid, pKa < 1 …
WebBefore proceeding with the calculation, we need to make sure the terms we ignored are negligible. We ignored the contribution from the autoionization of water to the hydroxide concentration; 1 x 10-7 + 5.01 x 10-4 is still equal to 5.01 x 10-4 so the 1 x 10-7 can be ignored. We also ignored the ionization change from the concentration of the hypochlorite …
