WebThe equivalence point is the point in a titration where the moles of acid are equal to the moles of base. At this point, the pH will be equal to 7.00 if a strong acid and strong base are used because strong acid and strong base react each other and formed salt and water . Webd. lowest absolute value: LiF, F2, HCl – only nonpolar molecule so it possesses only LD forces and will have the lowest freezing point e. lowest polarizability: Xe, NH3, HF – HF since it is the smallest, hardest species 2.
