Question

Write out the balanced chemical equation for the reaction of 2 moles of NaOH with 1 mole of H_3 PO_4. In this experiment, we didn't need an indicator because the pH electrode was attached to an interface, which allowed the computer to plot pH versus volume of NaOH delivered. This plot gave you the first two equivalence points. If you were trying to find the two equivalence points, what indicator solution(s) would you use? Do some research and suggest one indicator solution for each equivalence point. First equivalence point: Second equivalence point:

Explanation / Answer

2)

2NaOH + H3PO4 = Na2HPO4 + 2H2O

Phosphoric acid on treatment with two moles of sodium hydroxide giving rise to sodium hydrohen phosphate and water.
