What type of sediment was mainlyChosen to act as a buffer when dissolved

In water?

What is limestone?

4,4

True or False:Limestone acts as an alkaline buffer

Against the potential acidic conditionsProduced from the process of

Cell respiration.

What is TRUE: (cell respiration releases carbon dioxide gas)

5,1

Which organisms in your pond Produce the greatest amount of

Ammonia?

What are fish (in their urine)?

5,2

Ammonia produces alkaline conditions.Why is limestone NOT a good buffer

Against this process?

Limestone is also alkaline…only an acid could neutralize a base?
