11.2 Reactions Of Group 2 Elements

Question 1

How is the strength of reactivity of group 2 elements found?

Answer 1

By looking at reactions of group 2 metals with dilute hydrochloric acid forming solution of metal chloride and hydrogen gas

Question 2

How do elements in group 2 react with sulfuric acid?

Answer 2

React in a similar way to magnesium however any reaction with calcium strontium or barium is quickly stopped by the formation of an insoluble sulphate layer on the surface of the metals. Strontium sulphate less soluble than others
