suppose you added 40 ml of water to your vinegar sample instead of 20 ml would the titration have required more less or the same amount of NAOH for a complete reaction
Homework Answers
The titration would require the same amount of NaOH because even if the volume of water is increased, moles of acetic acid added (in vinegar) remain constant.
Adding the water decreases the concentration of acetic acid (in vinegar) but moles remain same.
These moles of acetic acid will require the same moles of NaOH added when the volume of water added was 20 mL.

1) Suppose you added 100 mL of water to your vinegar sample in the Erlenmeyer flask instead of 50 mL. Would the titration have required more, less or the same amount of NaOH for a complete reaction? Explain. 2)You used a 10.00 mL volumetric pipet to dispense the vinegar sample. Can you use a cylinder instead if it has the same precision?

Prelab Activity: Titrations Continued – Titration of Household Products A 2.40 g sample of vinegar was added to an Erlenmeyer flask along with 100 mL of deionized water and 3 drops of phenolphthalein indicator. It took 22.15 mL of 0.0981 M NaOH (aq) to reach the faint pink endpoint. The following balanced chemical equation represents the chemistry of the titration: NaOH (aq) + CH3COOH (aq) à CH3COO–Na+ (aq) + H2O (l) Calculate the mass % of acetic acid (CH3COOH) in...
