Question: A solution is prepared at 25C that is initially 0.42 M in an X base, a weak base with Kb = 7.4X10^-4, and 0.42 M

A solution is prepared at 25C that is initially 0.42 M in an "X" base, a weak base with Kb = 7.4X10^-4, and 0.42 M in conjugate acid "X". Calculate the pH of the solution. Round your answer to 2 decimal places. (Hint: pKw = pKa + pkb) I have not covered this concept in class. Thus it is worth 0 points
