1.	Consider an acidic buffer solution of acetic acid and sodium acetate at 25oC. What should be the ratio of concentration of sodium acetate and acetic acid so that pH=5 is obtained ?Given :Ka value of acetic acid is 1.8×10−5 log101.8=0.25 and 10(0.25)=1.8
Answer» Consider an acidic buffer solution of acetic acid and sodium acetate at $25^{o} C$ . What should be the ratio of concentration of sodium acetate and acetic acid so that $p H = 5$ is obtained ? Given : $K_{a}$ value of acetic acid is $1.8 \times 10^{- 5}$ ${log}_{10} 1.8 = 0.25 and 10^{(0.25)} = 1.8$
