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

What is the PH value of normal rain?*

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

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:
