Answer 1

(a) Distinfecting water in swimming pool by using ozone is a better way as compared to chlorine.
(b) Ozone is a more powerful oxidant and disinfectant than chlorine. Certain chlorine-resistant pathogens cannot multiply in water that is treated with ozone. Use of chlorine results in formation of unwanted products such as chloramines which irritates eyes and respiratory tract. Therefore, the quality of swimming water increases by use of ozone and a healthy swimming water is guaranteed.
