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. So, we need a CH3COONa to ...
WebJan 31, 2024 · What is the pH of ch3coo-na+ and NaOH? Now the mixture will acts as a salt CH3COO-Na+ of week acid CH3COOH and strong base NaOH.
