Electrochemistry form 4
A redox reactionis one in which reduction and oxidation processes occur simultaneously. Redox reactions involve electron gain and electron loss. Gain of electrons is a reduction process. The species that gains electrons is an oxidising agent. Loss of electrons is an oxidation process. The species that loses … See more An electrochemical cell is a device that generates a potential difference between electrodes using chemical reactions.

WebInstead, the copper in the copper anode ionises to form copper ions Cu2+. Cu→ Cu2+ + 2e. 2. During the electrolysis using copper electrodes, the copper (II) ions and hydrogen ion move to the cathode. Copper(II) ion is lower than hydrogen in the electrochemical series. Hence, in these copper ions are selectively discharged to form copper metal. WebThe course objective for Kenya Form 4 Chemistry is to: 1.
