The graph shows the titration of a polyprotic weak acid with a strong base. Label the following points.a. the point where the pH corresponds to a solution of H₂A in water b. the point where the pH corresponds to a solution of HA⁻ in water c. the point where the pH corresponds to a solution of A²⁻ in water d. the point where pH equals pKₐ₁ e. the point where pH equals pKₐ₂ **Graph Description:**- **Axes:** - The vertical axis represents pH, starting from approximately 0 and extending upwards. Important positions, such as pH 7, are marked on the axis. - The horizontal axis represents the volume of titrant added, measured in milliliters (mL).- **Titration Curve:** - The red curve illustrates the change in pH as titrant is added. - Initially, the curve is relatively flat and then rises steeply, indicating the endpoint of the first deprotonation. - It then levels off, rises again more steeply, signaling the endpoint of the second deprotonation, and finally levels off again.- **Points of Interest:** - Along the curve, there are several points marked with dotted lines leading to squares labeled with letters (a to e). - These points correspond to specific stages in the titration process, specifically where the solution is predominantly in the form of H₂A, HA⁻, or A²⁻, and where the pH is equal to the acid dissociation constants (pKₐ₁ and pKₐ₂).**Answer Bank:**- Labels: a, b, c, d, e.Each label from the answer bank corresponds to the specific points identified along the titration curve as described above.
