When you put a piece of magnesium
into water, bubbles of hydrogen gas are produced. The bubbles appear very, very slowly. It could take about a week to
collect enough hydrogen to 'pop'.
When you put a piece of magnesium
into dilute hydroelectric acid, hydrogen gas bubbles off quickly.
This shows that:
Magnesium reacts slowly with Water
and quickly with acid. A few metals react with water. More metals react with acid. The
Pictures show what happens when different metals are put
in acid and in water. Some metals react faster than magnesium. Some metals react more slowly'.
Some metals [the under-active metals’) don't
react at all.
The creativity series is a kind of
league table of metals. It puts the metals in order, with
the fastest reacting ones first. Potassium is at the top of the league. It reacts very quickly with water. If
it is put in acid, there is an explosion! Silver and gold are at the bottom of the league. They don't react with acid or water. The rest of the metals are in between. You can Work
out the order for yourself as you answer the questions.
