The titration of a 25.00 ML sample of 0.3 810M H3PO4 requires 21.24ml of NaOH what is the morality of the NaPH solution used

Answer:

0.4484 mol NaOH

Explanation:

To put it in simple terms, titration involves having the same number of moles of acid as the base. Therefore, you need to know the number of moles of the acid given the molarity and volume used, to know the molarity of base given its volume.

So nH3PO4 = 0.3810M*25ml = 9.525mol H3PO4 = 9.525mol NaOH

MNaOH = 9.525mol / 21.24ml = 0.4484mol NaOH
