12. calculate the hydroxide ion concentration of a solution with ph = 3.25. show all calculations leading to an answer

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
