Six plots should be constructed.Explanation / Answer
The plot of pH of water vs volume of HCl (mL) is shown below.
The plot of pH of buffer#1 vs volume of HCl (mL) added is shown.
The plot of pH of buffer#2 vs volume of HCl (mL) added is shown in the graph below.
The variation of pH of water with volume of NaOH added (mL) is shown in the graph below.
