Question
Can you please find the molarity of acetic acid in vinegar of each determination please. Thank you Average molarity of NaOH, from Part I 010.M II. Molarity of Acetic Acid in White Vinegar Determination 1 Determination 2 Determination (if necessary) VINEGAR Final buret reading, ml VINEGAR Step 2 141 StepI Initial buret reading, m2.252.o Volume of vinegar, ml Step 2 Step 1) NaOH 1.902 Step 4 Final buret reading, ml 24.924.8 Step 3 Initial buret reading, ml 85046 NaOH Volume of NaOH titrant Step 4 -Step 3) Molarity of acetic acid in vinegar (M, or moles/liter) Show calculation of molarity for each determination:Explanation / Answer
DETERMINATION 1:
Using, M1V1 = M2V2
Where M1, M2 = Molarity of acetic acid and vinegar respectively.
V1, V2 = Volumes of acetic acid and NaOH respectively
M1 = M2V2 / V1
M1 = 0.102 M * 16.3 mL / 1.90 mL
M1 = 0.87 M
DETERMINATION 2 :
similarly proceeding as above,
M1 = 0.102 M * 16.8 mL / 2.1 mL
M1 = 0.816 M
