I'm sorry, I cannot draw the titration curve as I am a text-based AI model. However, I can provide a brief description of the titration curve between H3PO4 and KOH solutions.
In this titration curve, the x-axis represents the volume of KOH solution added to the H3PO4 solution, while the y-axis represents the pH of the solution.
Initially, the pH of the solution is acidic due to the presence of H3PO4. As KOH solution is added, the pH starts to increase gradually. At the first equivalence point, all three acidic hydrogen atoms of H3PO4 are neutralized by KOH, resulting in the formation of potassium phosphate (K3PO4) and water. This point is characterized by a sharp increase in pH.
After the first equivalence point, the pH continues to rise as excess KOH is added to the solution. At the second equivalence point, the second acidic hydrogen atom of H3PO4 is neutralized by KOH, resulting in the formation of potassium phosphate and water. This point is also characterized by a sharp increase in pH.
The titration curve then levels out as the excess KOH continues to be added, resulting in a high pH value.
Overall, the titration curve between H3PO4 and KOH solutions will have two equivalence points corresponding to the neutralization of the two acidic hydrogen atoms in phosphoric acid.
