Which of the following is/are polluted? (a) Rain water, with pH 5.6 (b) The atmosphere contains 0.03 % CO_(2) (c) River water with a COD value 10 ppm (d) Pond water with phenomenon of eutrophication. The correct answer is

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. Name two main acids present in acid rain.
