An engineering team designs a rocket that flies faster and requires less fuel than any other model currently in production. However, the rocket is rarely
used because the type of fuel it requires is too costly. Which step of the
engineering process should have addressed this problem?

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.
