A certain metal ‘X’ lies between potassium and magnesium in the activity series.
Answer the following questions:
(a) What will happen when is added to cold water?
(b) What reaction will take place between X and dil. hydrochloric acid?
Since both potassium and magnesium lie above hydrogen in the activity series, these and also X are more reactive than hydrogen, therefore,
(a) X will react with water forming its hydroxide displacing hydrogen.
(b) X will react with hydrochloric acid liberating hydrogen and forming the chloride of X in solution.
