Answer to Question #56385 in General Chemistry for kelly
Calculate the [OH−] of aqueous solution with the pH = 11.0.
Express your answer using two significant figures.
[OH−] = ???
The sum of pH and pOH is equal 14, from it we can find pOH. pH + pOH = 14 pOH = 14 - pH = 14-11 = 3 From the formula for pOH calculation we can estimate the concentration of [OH-]. pOH = - log [OH-] [OH-] = 1x10^-3 M = 0.001 M
