Suppose you are titrating vinegar, which is an acetic acid solution, of unknown strength with a sodium hydroxide solution according to the equation
HC2H3O2+NaOH⟶H2O+NaC2H3O2HCX2HX3OX2+NaOH⟶HX2O+NaCX2HX3OX2
If you require 30.16 mL of 0.1428 M NaOHNaOH solution to titrate 10.0 mL of HC2H3O2HCX2HX3OX2 solution, what is the concentration of acetic acid in the vinegar?
Homework Answers
1 mol of acetic acid reacts with 1 mol of NaOH
From Molarity equation
M1V1 = M2V2
Where, M1 = Molarity of NaOH = 0.1428 M
V1 = 30.16 mL
V2 = 10.0 mL
So, 0.1428 M * 30.16 mL = M2 * 10 mL
M2 = 0.4307 M = concentration of acetic acid in vinegar

5, Vinegar should contain more than 4% acetic acid (CHCOOH, molar mass 60.0 g mor) 25.0 mL of vinegar are diluted to 100.0 mL and 10.0 mL samples of this solution are titrated against 0.100 mol L-NaOH solution. An average of 18.1 mL NaOH are required to neutralize the vinegar. You will need to calculate the concentration of the diluted solution and hence the percentage concentration of acetic acid in the original vinegar via the following questions: CH COOH(aq)...
