Jsing the table of the weak base below, you have chosen Ethylamine as your weak base in the buffen solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.52 M in this salt. The desired pH of the buffer should be equal to 10.1.

Using the table of the weak base below, you have chosen Ethylamine 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 0.52 M in this salt. The desired pH of the buffer should be equal to 10.1.
