6D.13 Rank the following solutions in order of increasing pH:
(a) 1.0 3 1025 m HCl(aq); (b) 0.20 m CH3NH3Cl(aq); (c) 0.20 m
CH3COOH(aq); (d) 0.20 m C6H5NH2(aq). Justify your ranking.

How do you do this?

B) C) D) are weak so you can calculate their pH using a regular ICE box.

A) is a strong acid so its pH is simply -log(0.00005)

How do you tell whether it is an acid or a base? And how do you tell whether it is a strong or weak acid?
