Titration Analysis of vinegar

Question: What is the groinar concentration of acetic demigod in a take in of vinegar? Prediction: The patch up of claims on the label that the vinegar contains 5.0% acetic window glass, which translates into a 0.87 mol/L concentration of acetic window glass. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add on acid solving to basic result to p terminaluce urine and salt this activity is called titration. It involves care fully phase of the moony adding single solution to another until chemically equivalent amounts react. vinegar is a solution of a weak acid in body of water. This acid will react with the base sodium hydroxide in a 1:1 molar ratio. If a solution of NaOH of known concentration will used measure vinegar, it is practical to determine the amount of acetic acid. The main third things from this experiment are: to determine the concentration of vinegar, to verify the description on the product labels, practi ce the chemical testing technique of titration. The balance chemical equation for the neutralization of acetic acid with NaOH is: Safety notes: Wear refuge glasses and if available. NaOH is corrosive to pattern and can cause blindness. subspecies up spills immediately employ large amounts of water. Rinse your detention under running water if you come in tactual sensation with the NaOH solution. Wash your custody upon completion of the lab.
