Answer to Question #68111 in General Chemistry for Mark
Question #68111
Describe what procedure you would follow to prepare a buffer solution to maintain a pH of 4.5?
Expert's answer
pH=pKk+lgVc/Vk
pKk=pKd(CH₃COOH)=4.756
Vc/Vk=x
4.5=4.756lgx
X=0.555
Vc/Vk=0/555
Vc=0.555Vk
100-Vk=0.555Vk
Vk=64.31
Vc=100-64.31=35.69
pKk=pKd(CH₃COOH)=4.756
Vc/Vk=x
4.5=4.756lgx
X=0.555
Vc/Vk=0/555
Vc=0.555Vk
100-Vk=0.555Vk
Vk=64.31
Vc=100-64.31=35.69
