Seamus Howe · Answer 1

Ph = 14 - POH = 14 - ( - log 4.3 * 10 - 4)

Ph = 14 - 3.37 = 10.63

10.63 is the answer

Dean · Answer 2

The hydroxide ion concentration = 4.3 X 10^-4 M

so we will calculate pOH first

pOH = - log[OH-] = - log (4.3 X 10^-4) = 3.37

we know that

pH + pOH = 14

so pH = 14-3.37 = 10.63
