Ph of poh
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. WebpH = −log [ H 3 O +] = −log ( 4.9 × 10 −7) = 6.31. pOH = −log [ OH −] = −log ( 4.9 × 10 −7) = 6.31. At this temperature, then, neutral solutions exhibit pH = pOH = 6.31, acidic solutions …
