Randall Diaz · Answer 1

PH is the negative logarithm of concentration of H+. But there is a relationship between pH and pOH.

pH + pOH = 14

pOH = 14 - pH = 14 - 6.47 = 7.53

Similarly, pOH is the negative logarithm of the concentration of OH-

pOH = - log (OH-)

7.53 = - log (OH-)

OH - = 2.95 x 10^-6
