Volume of oxygen required to burn 1.2 gm of C (carbon) at STP 

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

When a scientific theory has been tested and proved by the scientific community, it becomes a law
