Question

The soil in the taiga is acidic. This means that the soil has a

 

A) pH of 7

B) pH greater than 7

C) pH less than 7

D) none of these

 

I am a little lost and do not understand the question.

Answer 1

It has pH less than 7, 7 is neutral pH or rather ideal buffer pH. Anything less than & is moving towards acidic pH and anything above & is moving towards alkaline pH. 

 

Acidic pH requires some alkali to neutralize acidity and get  a neutral pH. Likewise alkaline pH requires strong or mild acid to neutralize alkali and bring solution to neutral pH.

 

Hope this is clear and helpful.
