Reactions of group 2 hydroxides with water

In this experiment we add water to small samples of Group 2 oxides and test the pH of the resulting solution. We then see if any further change occurs on adding dilute hydrochloric acid. Watch the video and make notes of your observations. Try to explain what you see and write balanced equations for any reactions. You may find the table of Group 2 solubilities will help to come up with a conclusion. You can check your answer in the theory link below.
