textbook 6d.13

Rank the following solutions in order of increasing pH: a) 1.0x10^-5 M HCl, b) 0.20 M CH3NH3Cl(aq), c) 0.20 M CH3COOH(aq), d) 0.20 M C6H5NH2

The answer key in the textbook does this question without any calculations but I don't know where they are getting the pH from? Can someone explain this to me

They are getting the pH by either finding the pKa or the Ka from the tables in 6C or 6D. They then set there ice table and continue solving for x. If you like I can post my calculations if you want a visual of how to solve for x and find the pH.
