Extraction of metals and the reactivity series. The most reactive metals are at the top of the series The tendency to become oxidised is thus linked to how reactive a metal is and therefore its position on the reactivity series Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation

Chemistry O Levelform Three Hardness Of Water

Calcium hydrogen carbonate is the most common cause of hardness of water.It forms when rain falls on the rocks of limestone and chalk, which are mainly composed of the insoluble calcium carbonate. As the rain falls through the air, it dissolves carbon dioxide to form weak acidic solution. This solution is able to attack the calcium carbonate to form the soluble calcium hydrogen carbonate.

Mar 08, 2021 The copper ions will be attracted towards the cathode because they are lower in the reactivity series than hydrogen. This means that the ease of discharge of copper ions is more than hydrogen ions. On the cathode, the copper ion will gain two electrons to become a copper atom. The equation below shows the reaction at the cathode Cu2 2e- Cu
