A chemistry student weighs out 0.0768g of ascorbic acid H2C6H6O6, a diprotic acid, into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1500M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Round your answer to 3 significant digits.
Molar mass of ascorbic acid = 176.12 g/mol
Moles of ascorbic acid = 0.0768 g/176.12 g/mol
= 0.000436 mol
As ascorbic acid is diprotic, it will require 2 mol of NaOH to neutralize one mol of ascorbic acid.
So, moles of ascorbic acid required = 2*0.000436
= 0.000872 mol
Volume of NaOH = moles/molarity
= 0.000872 mol /0.1500 mol/L
= 0.00581 L
= 5.81 mL
So, volume of NaOH required = 5.81 mL
