question_answer 1)

    The reaction: \[C{{l}_{2}}(g)+2O{{H}^{-}}(aq)\to Cl{{O}^{-}}(aq)+C{{l}^{-}}(aq)+{{H}_{2}}O(l)\] represents the process of bleaching. Identify and name the species that bleaches the substances due to its oxidizing action.

Answer:

  In the reaction : \[C{{l}_{2}}(g)+2O{{H}^{-}}(aq)\to Cl{{O}^{-}}(aq)+C{{l}^{-}}(aq)+{{H}_{2}}O(l)\]The hypochloride ion \[(Cl{{O}^{-}})\] acts as bleaching agent.
