Metals that are higher than H + ions on the Activity Series can be oxidized by the H + ions (i.e. The surface of this metal has a thin oxide layer that helps to protect it when it is exposed to acid. Neutralisation is the reaction between an acid and a base. Since a chemical reaction between an acid and a metal will produce hydrogen gas, this can be used to determine whether a particular metal has reacted with an acid or not. Was thinking maybe there is more than one answer that is correct? Acids only show their properties when dissolved in water. Solution: False.
