Correct Answer: Hydrogen peroxide


Solution : The correct option is Hydrogen peroxide.

In the paper industry, hydrogen peroxide (H 2 O 2 ) is often used for pulp bleaching. It is a non-toxic bleaching chemical that aids in the removal of colour, and residual lignin from the wood pulp during the papermaking process. In comparison to other chemical agents, hydrogen peroxide degrades into water, and oxygen, making it a safer and more sustainable alternative for pulp bleaching.
