Web9 aug. 2014 · Metals below hydrogen in the activity series are even less willing to give up their valence electrons. Instead, their ions remove valence electrons from hydrogen to form the metal atoms. For example, H₂ → 2H⁺ + 2e⁻ Cu²⁺ + 2e⁻ → Cu H₂ + Cu²⁺ → 2H⁺ + Cu WebThus carbon is above iron in the reactivity series (but, for the relative lack of reaction) only just above. This experiment can lead into a study of the blast furnaces. The ability of carbon to reduce metal oxides changes as the temperature rises. Web15 jun. 2024 · Copper ions are discharged in preference to hydrogen ions. Copper gains two electrons from the cathode and changes into an atom of copper. The atoms of copper are deposited at the cathode. The atoms of copper are deposited at the cathode ad form a layer of pink copper metal which gradually turns reddish brown. frozen two soundtrack on youtube
