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. Values of K, for Some Common Weak Bases Conjugate Acid Name Formula NH3 CH;NH2 C2H§NH2 CgH;NH2 C3H;N NH,+ CH;NH3* CH;NH3* CH;NH;* C3H;NH+ 1.8 × 10-5 4.38 × 10–4 5.6 × 10-4 3.8 × 10-10 Ammonia Methylamine Ethylamine Aniline Pyridine 1.7 x 10-9 3. Compute the concentration of the weak base in Molarity. (Write your answer in 4 decimal places without the unit).
