Using the table of the weak base below, you have chosen Aniline as your weak base in the buffer solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.71 M in this salt. The desired pH of the buffer should be equal to 3.8.    Compute the pOH of the buffer solution. (Write your answer in 1 decimal place).
