Explanation:
Detailed explanation-1: -A substance’s pH scales from 0 to 7, with 0 being the most alkaline and greater than 7 being the most acidic. Since carbon dioxide (CO2) dissolves in rain, generating weak carbonic acid, normal rain has a pH of about 5.6, making it somewhat acidic. The pH of acid rain typically ranges from 4.2 to 4.4.
