Interpretation:
The two main components of a buffer system should be identified.
Concept Introduction:
A buffer solution can be defined as an aqueous solution which is capable of resisting pH changes upon addition of small amounts of a strong base and a strong acid as well as upon dilution by distilled water (or in general water). The action that corresponds to keep the resistance to any changes on pH is known as “ buffering”. A buffer solution has a distinct definite pH value and hence is valuable in reaction conditions where one needs to maintain the pH value at a constant value. Blood is an example of a natural buffer which usually maintains the pH value around 7.4.

If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
