AlCl3, what is the molarity of
Cl−ions in the final solution? Q. What volume of 0.01 M H2SO4 must be added to 50ml of 0.01M NaOH solution to make a solution in which the molarity of the H2SO4 is 0.050M? Express your answer using two decimal places. Barium hydroxide is a strong base for both stages of dissociation: #"Ba"("OH")_2(s) -> "Ba"^{2+}+2"OH"^-# So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: #["H"^+]["OH"^-]=1.0xx10^{-14}"M"^# And then #"pH"=-log_{10}(["H"^+]=5.0xx10^{-14})=13.30#. |
