Question

all the rain that fall down is acid rain?​

Answer 1

Answer:

Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6. When the air becomes more polluted with nitrogen oxides and sulphur dioxide the acidity can increase to a pH value of 4. Some rain has even been recorded as being pH2.

Answer 2

Answer:

nope

not all the rain that falls down is acidic

rain has its own pH level

when the rain mixes with the oxides of sulphur and nitrogen its pH level decreases making it more acidic in nature
