Which of the following solutions will turn red litmus blue?
pOH 11.50,
2.3 × 10−4 M [OH−],
pH 5.50 or
4.1 × 10−5 M [H3O+]
Solution
 2.3 × 10−4 M [OH−],Â
tip: pH = 14 - pOH = 14 -(-log(2.3x 10-4) = 14-3.64 = 10.36 > pH = 7. The solution is basic and thus has turn red litmus blue. all the other cases, pH < 7 and thus they are acidic.
