7. Describe a buffered solution. Give three examples of buffered solutions. For each of your examples, write equations and explain how the components of the buffered solution consume added strong acids or bases. Why is buffering of solutions in biological systems so important?
Interpretation:
The buffered solution is to be described. The three examples of the buffered solution are to be stated. The example which shows the components of the buffered solution consume added strong acids or bases is to be explained with equations. The reason corresponding to the fact that the buffering of the solution is important for the biological system is to be stated.
Concept Introduction:
Buffer solution resists the change in
Buffer solution has a constant value of
The examples of the buffer solution are,
Assume that the acid buffer solution of acetic acid and sodium acetate. The dissociation of sodium acetate is shown below.
The solution contains the sodium ions, acetate ions and some amount of undissociated acetic acid molecules.
Hydrochloric acid is a strong acid and it dissociates completely.
If some drops of hydrochloric acid is added to this solution. It provides hydrogen ions to the buffer solution
