WebSo, we need a CH3COONa to be 0.1 M. On a Liter basis, then, we will have to add 8.2 g of CH3COONa (0.1 mol). For the second case (pH = 5), the conditions will be pKa = 4.76, pH = 5, [A-] = [CH3COONa] = x, [CH3COOH] = 0.1 M. Putting into the numbers and. 5 = 4.76 + log x/0.1 0.24 = log x/0.1 1.74 = x/0.1 ==> x = 0.174.
