Reactions of Group 2 metals with acid

Question 1

Reactions of Group 2 metals with acid
The Group 2 metals will react with dilute acids to form

Answer 1

colourless solutions of metal salts
For example, they will form colourless solutions of metal chlorides if reacted with hydrochloric acid

Question 2

When metals react with an acid, the by-product of this reaction is

Answer 2

hydrogen gas

Question 3

The reaction of the metals with dilute HCl follows the following general equation

Answer 3

M (s) + 2HCl (aq) → MCl2 (aq) + H2 (g)

Question 4

The reaction of the metals with dilute H2SO4 follows the following general equation:

Answer 4

M (s) + H2SO4 (aq) → MSO4 (aq) + H2 (g)

Question 5

The reaction of the metals with dilute H2SO4 follows the following general equation

remember that SrSO4 and BaSO4 are insoluble

so

Answer 5

They are solids in the products state symbol

Question 6

Exam Tip
Learn the general equation for the reaction with water and for magnesium with steam. You could be asked or reactions of the oxides and hydroxides with acids.
