In acid rain, the pH of rain water falls belowQuestion 11AnswerA.6.2B.7C.5.6D.6

At which pH would the rain classify as acid rain:Question 1Select one:a.pH ≤ 6b.pH ≤ 7c.pH ≤ 8d.pH ≤ 5e.pH ≤ 3

What is the PH value of normal rain?*

Rainwater was collected at thirty different sites near an industrial basin and the amount of acidity (pH level) was measured. The pH values were:2.6, 2.7, 2.9, 3.2, 3.3, 3.7, 3.7, 3.8, 3.9, 4.1, 4.2, 4.2, 4.2, 4.4, 4.4,4.6, 4.8, 4.9, 4.9, 5.0, 5.5, 5.5, 5.6, 5.7, 5.8, 5.8, 6.0, 6.2 6.3, 6.3The interquartile range is:

Calculate the acid concentration of a sample of acid rain with a pH of 4.20.Group of answer choices4.2 × 10-1M7.7 × 10-9M6.3 × 10-5M0.62 M 1.0 × 10-4M

H2CO3 is not considered as a component of acid rain because ans. It decreases the pH level of water negligibly small amount. It is not an acid. It is not produced during precipitation. It is harmless to aquatic plants and animals.
