questions are in red Consider the following salt solutions: (i) NH4Cl – NH+ + C- Notice that as a salt, NH,Cl dissociates completely in solution. So, what are the parents of this salt? The cation, NH, in this case, is from the base obtained by adding enough OHto balance the positive charge(s) on the cation; Viz, NH,OH. Similarly, the anion, Cl. comes from the acid. So the parent acid can be obtained by adding enough Hi to neutralize the charge...
