Question
For preparing a buffer solution of pH 6 by mixing sodium acetate and acetic acid, the ratio of the concentration of salt and acid should be (Ka = 10 –5)
Answer: B
💡 Solution & Explanation
pH = 6 therefore the solution is an acidic buffer. Using Henderson Hassel Balch equation. a salt pH = pK + log acid 5 a a K = 10 pK = 5 salt 6 5 log acid salt log 1 acid salt 10 acid 1 salt : acid 10 :1
