acids reacting with metals

Question 1

what do all acids contain

Answer 1

hydrogen

Question 2

in all acid reactions, what is displaced

Answer 2

the hydrogen

Question 3

explain the displacement reaction of

sulphuric acid + magnesium

Answer 3

the magnesium displaces the hydrogen from the sulphuric acid
making magnesium sulphate (salt) and hydrogen gas

sulphuric+magnesium->magnesium+ hydrogen
acid sulphate

Question 4

what is the equation for acids reacting with metals

Answer 4

Acid + metal —> salt + hydrogen

Question 5

how 2 acids react with metals (important question)

hydrochloric acid reacts to produce what

sulphuric acid reacts to produce what

Answer 5

produces salts ending with chloride

produces salts ending with sulphate

Question 6

how 3 different metals react with the acids (important)

what are the 3 different metals that react with hydrochloric acid and sulphuric acid

Answer 6

zinc
magnesium
iron

Question 7

show magnesium reacting with hydrochloric acid

show magnesium reacting with sulphuric acid

Answer 7

hydrochloric acid + magnesium —> magnesium chloride + hydrogen

sulphuric acid + magnesium —> magnesium sulphate + hydrogen

Question 8

how does magnesium react with acids?

why?

Answer 8

rapidly
magnesium is much more reactive than hydrogen in the reactivity series meaning it can easily displace hydrogen from acids

Question 9

why might iron have a fairly slow reaction with acids

Answer 9

it’s closer to hydrogen in the reactivity series making it only slightly more reactive and slower to displace
