Chemistry Investigation Introduction In this investigation we will find out which two metals combined together give the higher voltage when reacting with acid. The metals used will be: * Aluminium * Zinc * Iron * Tin * Lead * Nickel * Copper To make a prediction on what metals will be the ones that give the highest voltage when combined together you need to find out if the position in which the metals are at in the reactivity series would make a difference, and if it does, how? You also need to find out how the metals react with acids. We know that the higher the metal is in the reactivity series, the stronger it will react with an acid. Theory Batteries have chemicals inside to store energy. When two different metals that are connected by a wire are placed into an acid, a potential difference (voltage) is produced. This occurs because the metals react with the acid forming Hydrogen acid,...
