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 exhibit pH less than 6.31 and pOH greater than 6.31, whereas basic solutions exhibit pH greater than 6.31 and pOH less than 6.31.
WebpH = − log[H +] pOH = − log[OH −] pKw = − log[Kw] At room temperature, Kw = 1.0 × 10 − 14 So pKw = − log[1.0 × 10 − 14] = 14 Using the properties of logarithms, Equation 1.17.8 can be rewritten as 10 − pKw = 10 − 14. The equation also shows that each increasing unit on the scale decreases by the factor of ten on the concentration of H +.
