Which of these conjugate acid-base pairs will not function as a buffer? a) hno3 and no3^-b) hco3^- and co3^2-c) c2h5cooh and c2h5coo^-

Answer;

A) HNO3 and NO3^-

Explanation;HNO3 is a strong  acid and NO3 is its conjugate base, meaning it will not have any tendency to withdraw H+ from solution.Buffers are often prepared by mixing a weak acid or base with a salt of that weak acid or base.The buffers resist changes in pH since they contain acids to neutralize OH- and a base to neutralize H+. Acid and base can not consume each other in neutralization reaction.
