Rank these solutions from the most alkaline (1) to the least alkaline (5). pOH = 0.5 pH = 3.5 [OH–] = 5.62 × 10–5 M [H3O+] = 3.16 × 10–7 M pH = 0.5

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —

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.

What information does a complete ionic equation give that the balanced equation doesn’t show?
