Which one of the following statement is not true ?
1 \(pH\) of drinking water should be between \(5.5 - 9.5\)
2 Concentration of \(DO\) below \(6\, ppm\) is good for the growth of fish.
3 Clean water would have a \(BOD\) value of less than \(5\, ppm.\)
4 Oxides of sulphur, nitrogen and carbon, are the most widespread air pollutant.
Explanation:
Growth of fish is inhibited if concentration of \(DO\) is below \(6\,ppm\).

Which one of the following statements is not true ?
1 Clean water would have a \(BOD\) value of \( 5\, ppm.\)
2 Fluoride deficiency in drinking water is harmful. Soluble fluoride is often used to bring its concentration upto \(1\, ppm.\)
3 When the \(pH\) of rain water is higher than \(6.5,\) it is called acid rain.
4 Dissolved Oxygen \((DO)\) in cold water can reach a concentration upto \(10\, ppm.\)
Explanation:
The correct option is \(C\). When the \(pH\) of rain water is higher than \(6.5\), it is called acid rain. When \(pH\) of ran water drops below \(5.6\) it is called acid rain.
