WebThe value of Kw is exactly 1.0 x 10^-14. This value can be used to calculate pH and pOH. Also -logKw = 14 is the value that is when fed into the equation will give you pH and pOH depending upon the concentration you use. But the most efficient way to do so is commencing to our free pH calculator. WebYou can't calculate pOH straight from Kb; can only do so if you're given [OH-]. Since you're not given this, you have to find it. So use ICE chart for the base dissociation: NH3 + H2O …
