Answer is Wrong!
Answer is Right!
The correct answer is B. 5.6.
Rainwater is slightly acidic due to the presence of carbon dioxide in the atmosphere. When carbon dioxide dissolves in water, it forms carbonic acid. The pH scale ranges from 0 to 14, with 7 being neutral. A pH below 7 is acidic, and a pH above 7 is basic. Rainwater typically has a pH of 5.6, which is slightly acidic.
Option A is incorrect because a pH of 3.2 is very acidic. Option C is incorrect because a pH of 6.3 is neutral.
