1. The problem statement, all variables and given/known data A buffer solution was formed by mixing 30ml of 0.1M sodium acetate and 15ml of 0.1M HCl a) Calculate the pH of this buffer solution. b) Calculate the pH of this buffer solution after the addition of 15ml of 0.1M HCl. 2. Relevant equations pH = pKa + log[salt]/[acid] 3. The attempt at a solution for part a) I substituted the value in the above equation as pKa= 4.75 for acetic acud. [salt]=0.1 and [acid]=0.1 and got pH as 4.75 Is it right ? and I'm stuck with part B) can anyone please help me .... please soon!
