In the reactions given below, identify the species undergoing oxidation and reduction:
Justify that the reaction: 2 Na(s) + H2(g) → 2 NaH (s) is a redox change.
While sulphur dioxide and hydrogen peroxide can act as oxidising as well as reducing agents in their reactions, ozone and nitric acid act only as oxidants. Why ?
The compound AgF2 is unstable compound. However, if formed, the compound acts as a very strong oxidising agent. Why ?
Whenever a reaction between an oxidising agent and a reducing agent is carried out, a compound of lower oxidation state is formed if the reducing agent is in excess and a compound of higher oxidation state is formed if the oxidising agent is in excess. Justify this statement giving three illustrations.
Identify the substance oxidised reduced, oxidising agent and reducing agent for each of the following reactions:
