Rohan heard that instructions were given to the laboratory attendant to store a particular chemical i.e., keep it in the dark room, add some urea in it, and keep it away from dust. This chemical acts as an oxidising as well as a reducing agent in both acidic and alkaline media. This chemical is important for use in the pollution control treatment of domestic and industrial effluents.

(i) Write the name of this compound.

(ii) Explain why such precautions are taken for storing this chemical.

<p><span data-teams="true">This is a short answer type question as classified in NCERT Exemplar</span></p><p><span data-teams="true"><strong> (i) </strong>The given compound is H₂O₂.</span></p><p><span data-teams="true"><strong> (ii)</strong> Textiles, paper pulp, leather, oils, fats, and other products use it as a bleaching agent. In both acidic and alkaline media, it works as an oxidising and reducing agent. It is therefore kept in dark wax-lined glass or plastic containers. As a stabiliser, urea might be used. It is kept away from dust since dust can cause the compound to decompose explosively.</span></p>
