This soidum hydroxide solution was then used to determine the amount of acetic acid in vinegar. Three titrations of the sodium hydroxide solution against exactly 5mL of vinegar using phenolphthalein indicator required 22.85Ml, 22.67mL and 22.93mL of the sodium hydroxide solution. What is the molarity of the acetic acid in vinegar?

The molarity of sodium hydroxide solution is .347M

1 answer

volumebase*molaritybase=volumeacid*molarityacid

I would add the three volumes given,usw 15ml for volume acid, thensolve for Molarityacid
