Answer:

All the METALS react with dilute hydrochloric acid to give bubbles of hydrogen and a colourless solution of the metal chloride.

As you might expect for elements in this part of the Periodic Table, the reactions get more vigorous as you go down the Group.

Reactions with dilute sulphuric acid

These are more complicated, because of the formation of insoluble sulphates.

Beryllium and magnesium

These are just like the reactions with dilute hydrochloric acid, and you have probably been familiar with the REACTION between magnesium and dilute sulphuric acid almost since you started doing chemistry. Bubbles of hydrogen are formed, together with colourless SOLUTIONS of beryllium or magnesium sulphate.

For example:

Calcium, strontium and barium

Calcium sulphate is sparingly soluble, and you can think of strontium and barium sulphates as being insoluble. That means that you will get a LAYER of insoluble sulphate on all of these which will SLOW down the reaction or stop it entirely.

In the calcium case, you will get some hydrogen produced together with a white precipitate of calcium sulphate.
