Question

1)state the purpose of development pH scale
2)mention the pH range of acids
3)what is pH of acid rain how it affects the aquatic life

Answer 1

SO MATE..
THE ANSWER IS
1. The pH scale ranges from 0 -14 .. so from 0-6 it's acidic. At 7 it's neutral . 8-14 it's basic.
2. It ranges from 0 to 6
3. The pH of acid rain is about 3-5 as it includes harmful acids like Sulphuric acid, Nitric acid, etc..
The aquatic life is living and near neutral water ( pH 7 )to sustain and make food.. so it the pH is low they can't get enough oxygen and hence can die...

HOPE THIS ANSWER HELPS..

Answer 2
