Question

Which ion acting as oxidising agent and reducing agent?

Answer 1

Answer:

1] the electropositive ions [cations] are oxidising agent

2] the electronegative ions [anions] are reducing agents

Explanation:

1] metals give away electrons in order to have a complete electronic configuration thus forming a cation and losing of electrons is oxidation reaction thus cations are oxidising agent

2] non metals [generally] gain electrons in order to have a complete electronic configuration thus forming an anion and gaining of electrons is reduction reaction thus anions are reducing agents

Answer 2

Answer:

cations are oxidising agents and anions are reducing agents
