Question

What happens when small amounts of acid or base are added to a buffer solution? What would happen if these solutions were not buffered? What conclusions can you draw about buffer solutions?  

Answer 1

Ans- A buffer solution is such a solution which has a tendency to resist change in pH when small amounts of acid or base are added to it.

So as per the definition itself, an adding amount of acid and base, the pH of buffer solution generally remains same or changes very little.

If the solution were not buffer, on adding acid it's pH would have decreased and on adding base it's pH would have increased.

So we draw rhe conclusion that buffer solution actually helps in resisting change in pH and has a vast number applications in our day to day life. Example- blood is a buffer.
