Explanation / Answer

Acidic nature or alkaline nature is measured by ph levels .

Which ranges from 1-14 . Where ph level 7 is said to be neutral . We say it acidic when ph level drops down from 7 and it is said to be alkaline if ph level goes up from 7 that is towards 14.

Too much of any thing is bad ,so we need to maintain balance ..that's why we try to keep ph level at 7 which is neutral.

Any thing increases either acidic or alkaline both are hazardous to life. If there is acidic rain falls it makes soil mixed with aluminum which destroy important nutrients of the soil as a result tree are unable to absorb water from soil which is essential for growth.
