Use the simulation to observe the reactivity of magnesium in each solution. FOR EACH BEAKER, FIRST record if a reaction takes place or does not take place. SECOND If a reaction takes place, record ALL your observations by choosing from the list of options. If there is no obvious change to the colour of a solution or the piece of metal, then no observation about the solution or piece of metal needs to be made.
