Strong and Weak Acids - Reaction Rate
When magnesium is put into an acid
it will react and produce hydrogen gas (see more information).
The more concentrated the acid, the faster the magnesium will react
and you will see more bubbles of hydrogen
being produced.
A strong
acid and a weak acid of the same
concentration
will react at
different rates with the same metal.
You can see the difference between
a strong acid and a weak acid of the
same concentration
by looking at the reaction with
magnesium.
The strong acid will react faster and you
will see
more bubbles of hydrogen
being produced.
This is because the strong acid has
more hydrogen
ions present in solution
even though it is at the
same concentration as the weak acid.
A piece of magnesium the same size should be
used
in both acids for the comparison to be fair.
The weak acid will
produce the same amount of
hydrogen as the strong acid
from the same amount of magnesium
but the weak acid will take longer to do it.
