The pOH value of solution will be -5.54.
By calculating the concentration of OH ions in a solution, pOH can be used to gauge how acidic or alkaline a solution is. The OH ion concentration's negative logarithm would be known as pOH.
Given that:
pH = 7.5
kw = 8.48×[tex]10^{-14}[/tex]
pH = - log [[tex]H^{+}[/tex]]
[[tex]H^{+}[/tex]] = [tex]10^{-pH}[/tex]
Put the value of pH in above equation.
[[tex]H^{+}[/tex]] = [tex]10^{-7.5}[/tex]
[[tex]H^{+}[/tex]] = 3.16 × [tex]10^{-8}[/tex]
Put the value of given data in above equation.
[[tex]OH^{-}[/tex]] =Kw / [tex][H^{+} ][/tex]
[[tex]OH^{-}[/tex]] = 8.48×[tex]10^{-14}[/tex] / 3.16 × [tex]10^{-8}[/tex]
[[tex]OH^{-}[/tex]] = 2.6 × [tex]10^{-6}[/tex].
pOH = -log [[tex]OH^{-}[/tex]]
pOH = =log [ 2.6 × [tex]10^{-6}[/tex]]
pOH = log [2.9] - 6log 10
pOH = 0.46 -6
pOH = -5.54
Therefore, the pOH value will be -5.54
