Question

Cu2+ + Ni Cu + Ni2+

In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.

name of the element oxidized:

  
name of the element reduced:

  
formula of the oxidizing agent:

formula of the reducing agent:

As the reaction proceeds, electrons are transferred from

to

.

Answer 1

The reaction is: Cu+2 + Ni --------------> Cu + Ni+2

In the above redox reaction, the oxidation state of nickel is increased from 0 to +2 and the oxidation state of copper is decreased from +2 to 0

Name of the element oxidized : Nickel

Name of the element reduced : Copper

Formula of the oxidizing agent: Cu+2 (oxidizing agent means the metal which is reduced)

Formula of reducing agent : Ni (metal which is oxidized is a reducing agent)

Electrons are transferred from Nickel to Copper.
