Redox Reactions...

The term oxidation was coined for the class of chemical reactions wherein one of the following options take place.

The term reduction has one of the following options taking place.

Oxidation and reduction always occur simultaneously, hence, the word “redox” was coined for this class of chemical reactions. In the following redox reaction, identify the species undergoing oxidation and reduction: 3Fe₃O4(s) + 8 Al (s) → 9 Fe (s) + 4Al₂O₃(s)

Copper nitrate is a blue coloured solution. Place a strip of metallic zinc in an aqueous solution of copper nitrate for about one hour. What happens?

Identify the correct statement (s) in relation of the following reaction:

Zn + ₂HCl → ZnCl₂ + H₂

In the reaction of metallic cobalt placed in nickel sulphate solution, there is a competition for release of electrons At equilibrium, chemical tests reveal that both Ni²⁺ (aq) and Co²⁺ (aq) are present at moderate concentrations. The result is that:

Oxidation number denotes the oxidation state of an element in a compound ascertained on the basis that electron in a covalent bond belongs

The highest value of oxidation number changes from 1 to 7
