Question

Q7. Carbonic acid and bicarbonate ion are an conjugate aicd-base pairs. For each of the following compounds, would the carbonic acid or bicarbonate be more likely to react with them and serve as a buffer to prevent pH change?
a. HBr
b. LiOH
C. NH4+
d. HCOO
e. CH3NH2​

Answer 1

Explanation:

A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0.

Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ions or OH– ions, thereby maintaining an overall steady pH in the solution.

pH is equal to the negative logarithm of the concentration of H+ ions in solution: pH = – log[H+].
