(thanks Lynn! Aluminium metal will react with dilute hydrochloric acid to produce aqueous aluminium chloride, "AlCl"_3, and hydrogen gas, "H"_2. This means that is has a higher potential to be reduced (gain electrons) and is therefore less likely to be oxidized (lose electrons), which is what would need to happen for it to displace hydrogen.  For the sake of discussing the reaction, here's what the equation would look like if the reaction did take place: `2Cu + 2HCl -> 2CuCl + H_2` , E = 0.159 V. Both of these reactions have a positive standard reduction potential (E) compared to hydrogen, which is zero volts. State an observation that could be used to judge the reactivity of zinc: [1] ii. Metals to the left of hydrogen in the series lose electrons when they ionize, whereas those to the right, which do not react with hydrochloric acid, gain electrons when they ionize. The cage for the Mg metal is used to either lower the Mg into the acid solution, or to hold it at the bottom of the column of acid and keep it from floating upward.
