The following pH curve is for the titration of 20.0 mL of a 0.10 M solution of a weak monoprotic base with a 0.10 M solution of a strong monoprotic acid.**Graph Description:**- **Y-Axis (Vertical):** Represents the pH level, ranging from 0.0 to 12.0.- **X-Axis (Horizontal):** Represents the Volume of titrant in mL, ranging from 0.0 to 50.0.- The curve starts at a high pH and decreases as the volume of titrant increases. The initial section of the curve is relatively flat, indicating that the pH changes slowly. As the titration proceeds, there is a steep drop in pH, indicating the equivalence point. After the equivalence point, the curve flattens out again, showing a more gradual pH decrease.**Data points are plotted at 1 mL increments.****Questions:**(a) What is the pH before any titrant has been added? (b) What is the pH at the midpoint of the titration? (c) What is the pH at the equivalence point? (d) What is the value of \( K_b \) for the weak base?
