Explanation:
The Reaction of Metals with Dilute Acid.
Potassium, sodium, lithium and calcium all react violently
with dilute sulfuric acid and dilute hydrochloric acid.
It is dangerous to put these metals into an acid.
The reaction is similar to the reaction with water,
forming the metal salt (either sulfate or chloride) plus H2(g).
For example
sodium + hydrochloric acid arrow sodium chloride + hydrogen.
2Na(s) + 2HCl(aq) arrow 2NaCl(aq) + H2(g)
Magnesium, aluminium, zinc, iron, tin and lead
react safely with dilute acid.
Magnesium is the fastest and lead is the slowest of the six.
magnesium + sulfuric acid arrow magnesium sulfate + hydrogen.
Mg(s) + H2SO4(aq) arrow MgSO4(aq) + H2(g)
magnesium + hydrochloric acid arrow magnesium chloride + hydrogen.
Mg(s) + 2HCl(aq) arrow MgCl2(aq) + H2(g)
(see how to measure the rate of the reaction)
aluminium + hydrochloric acid arrow aluminium chloride + hydrogen.
2Al(s) + 6HCl(aq) arrow 2AlCl3(aq) + 3H2(g)
zinc + sulfuric acid arrow zinc sulfate + hydrogen.
Zn(s) + H2SO4(aq) arrow ZnSO4(aq) + H2(g)
iron + hydrochloric acid arrow iron(II) chloride + hydrogen.
Fe(s) + 2HCl(aq) arrow FeCl2(aq) + H2(g)
tin + hydrochloric acid arrow tin(II) chloride + hydrogen.
Sn(s) + 2HCl(aq) arrow SnCl2(aq) + H2(g)
lead + sulfuric acid arrow lead sulfate + hydrogen.
Pb(s) + H2SO4(aq) arrow PbSO4(s) + H2(g)
The reaction of zinc with sulfuric acid is often used to
make a small amount of hydrogen in the laboratory - see moles.
The reaction is slow at room temperature
but its rate can be increased by the
addition of a little copper(II) sulphate.
Zinc displaces copper metal, which acts as a catalyst.
Metals below hydrogen in the reactivity series
(copper, silver, gold and platinum) will not react with dilute acid.
They cannot displace hydrogen from the non-metal anion.
