    1. Calculate the pH of a solution that is prepared by mixing 45 ml of 0.224 M chlorobenzoic (3-) acid with 30 ml of 0.187 M ethylamine.

     

     

    1. Calculate the pH of a solution that is prepared by mixing 75 ml of 0.088 M aniline with 50 ml of 0.097 M nitrophenol (2-).

     

     

    1. What is the typical range of Ka and Kb values for weak acids and bases? Which value represents the weakest and which the largest?  What would be the pH of solutions 0.1 M in the acid or base at the extremes of the range?
