Lab $10$: Determination of the Concentration of Acetic Acid in Vinegar

Determination of the Concentration of Acetic Acid in Vinegar

$2.$ A $10\mathrm{.}00mL$ aliquot of vinegar is titrated with the same NaOH solution standardized in Question $1.$ The titration curve below is for the titration of vinegar with the standardized NaOH solution. See Eq$.6$ for the balanced equation for the reaction.

a$.$ Determine the number of moles of NaOH required to neutralize the acetic acid in the vinega sample.

$14\mathrm{.}7K$ Mof $Na{O}^H=0\mathrm{.}575m$

$=0\mathrm{.}5750\mathrm{.}0147=0\mathrm{.}00845$mole

b$.$ Determine the number of moles of $C{H}_3\frac{C}{O}OH$ in the vinegar sample.

$\frac{0\mathrm{.}00845}{14\mathrm{.}7}m$
