true or false _ When concentration has unit of mol/L, its activity has the same unit.  Further,  usually the value of activity is smaller than that of the corresponding concentration.   6  __ Because of the Zwitterion structure,  amino acids are usually considered as diprotic or even triprotic acids.   7.__ The fractional composition of any species from the dissociation of a weak acid always depends on the              solution pH.
