Why it is necessary to make paste first before making solution of bleaching powder?

Making a paste of bleaching powder before dissolving it in water is necessary to ensure even distribution and prevent clumping. The paste allows for better interaction between the powder and water, facilitating a more uniform solution. This method enhances the solubility of the bleaching powder and ensures that the active chlorine is effectively released for its intended use. Additionally, it minimizes the risk of creating hazardous dust during the mixing process.
