Oxidising and reducing agents

Question 1

Reducing agent

Answer 1

• metal or negative ion
• loses electrons to another element or ion
• is itself oxidised

Question 2

Example of reducing agent, sodium is a reducing agent which is itself oxidised as follows:

Answer 2

+ -
Na (s) => Na (aq) + e

Question 3

Oxidising agents

Answer 3

• non-metal or positive ion
• oxidation reactions to take place
• gains electrons from other ions (is itself reduced)

Question 4

Oxidising agents, Example: chlorine and copper ions are both oxidising agent which are themselves reduced as follows:

Answer 4

• -
  Cl (g) + 2e => 2Cl (aq)
  2

 2+            - Cu (aq) + 2e => Cu(s)

Question 5

Redox reactions

Answer 5

One in which both oxidation and reduction take place
