Acidity 10. What is it about the region of the graph you picked in the previous question (A or B)
that shows you that buffering is happening at that region? e are snailan
Solution
Area B is showing that buffering is happening in that at that region because a buffer is a solution
containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes
in pH. Above plot shows how the buffer capacity changes in the B region after adding a small
amount of HCl.
