प्रश्न
Write two uses of ClO2.
उत्तर १
1) ClO2 is an excellent bleaching agent. It is 30 times stronger bleaching agent then the Cl2. It is used as a bleaching agerit for paper pulp in paper industry and in textile industry
2)ClO2 is also a powerful oxidising agent and chlorinating agent. It acts as a germicide for disinfecting water. It is used for purifying drinking water.
उत्तर २
