Which of the following methods could be used to prepare a buffer solution? (more than 1 answers)
Question 6 options:
Partially neutralize a weak acid solution by addition of a strong base.
Add appropriate quantities of a weak acid and its conjugate base to water.
Partially neutralize a weak base solution by addition of a strong acid.
Partially neutralize a weak base solution by addition of a strong base.
Partially neutralize a weak acid solution by addition of a strong acid.
Partially neutralize a weak acid solution by addition of a strong base.
Add appropriate quantities of a weak acid and its conjugate base to water.
Partially neutralize a weak base solution by addition of a strong acid.
Partially neutralize a weak base solution by addition of a strong base.
Partially neutralize a weak acid solution by addition of a strong acid.
Explanation / Answer
1) Partially neutralize a weak acid solution by addition of a strong base.
as an example >> CH3COOH(weak acid) +NaOH(strong base)>>CH3COONa +H2O
weak acid conjugate base
3) similarly
Partially neutralize a weak base solution by addition of a strong acid.
2)
Add appropriate quantities of a weak acid and its conjugate base to water. is also a same condition as in option (1)
1) Partially neutralize a weak acid solution by addition of a strong base.
as an example >> CH3COOH(weak acid) +NaOH(strong base)>>CH3COONa +H2O
weak acid conjugate base
