What property would you use to tell similar liquids apart?

A buffer solution is 0.100 m in both hc7h5o2 and kc7h5o2 and has a ph of 4.19. What ph values would you expect from the addition of a small amount of a dilute solution of a strong base?

How does the complete filling of a subshell affect E? produces chemical stability; therefore increases E produces chemical stability; therefore decreases E no apparent effect E becomes very high because the atom becomes inert
