What is a possible ph of acid rain?
7.0
6.9
4.3
10.5

Answer : The correct option is, 4.3

Explanation:

Acid rain : It is formed by a chemical reaction when sulfur dioxide and nitrogen oxides are released into the air.

The pH range is, 1 to 14.

When the value of pH is less than 7 then the solution is acidic.

When the value of pH is more than 7 then the solution is basic.

When the value of pH is equal to 7 then the solution is neutral.

The pH of normal clean rain in between 5.0 to 5.5 which is partially acidic.

When rain combines with sulfur dioxide and nitrogen oxides then the rain becomes more acidic and the pH of acidic rain is, 4.0

Hence, the correct option is, 4.3

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
