Question

. Which of the following solutions has the greatest buffering capacity and which one has the least? a. 0.01 M HAc and 0.01 M

science chemistry

Answer 1

Answer #1

Buffer capacity is greatest when there are equal amount of acid and conjugate base ( salt)

a. 0.01M HAc and 0.01M NaAc PH = 4.74

c.0.1M HAc and 0.1M NaAc PH = 4.74

a,c are greatest buffer capacity.

b. 1.8*10^-5 M HBr PH = 4.74

HBr is strong acid . It is not buffer solution.so It has least buffer capacity

b. b. 1.8*10^-5 M HBr PH = 4.74 has least buffer capacity >>>>answer
