Problem- You have a 0.145 M aqueous KOH solution. You also have 253 mL of a 0.0412 M aqueous H3PO4 solution.
After 45.0 mL of the KOH solution are added to the H3PO4 solution,
1) Determine the moles of H3PO4 present in the container at this point.
2) Determine the moles of potassium phosphate present in the solution at this point.
3) Determine the molarity of H3PO4 at this point.
4) Determine how many mL of your KOH solution would be needed to titrate all of your H3PO4.
I want you to elucidate the chemistry in this above problem.
