Determination of Percentage Acetic Acid in White Wine

User Description:
Volumetric analysis is a common technique used by analytical chemist. Titration (Fig 1) is the method of determining the concentration of an unknown concentration of acid or base, this is done by mixing the known concentration which is standardized to the unknown concentration which is unstandardized

Sample Text:
Determine the HCl solution concentration with your standard solution of Na _ CO , 2. Determine the NaOH solution concentration with the newly standardised HCl. 3. Determine the acid concentration in white wine with the newly standardised NaOH. 4. Determination of the percentage by mass of acetic acid in the white wine. In this practical, the known concentration of Sodium Hydroxide (NaOH) was used to determine the unknown concentration of acetic acid (CH , COOH) in the white wine. Therefore, Titration was done to neutralise 20ml of white wine from Sodium Hydroxide (NaOH). NaOH (aq) + CH 3 COOH (aq) → CH 3 COOHNa (aq) + H 2 O (l) Aim: To determine the percentage of acid in white wine, assumed it is all acetic acid. Background knowledge: Volumetric analysis is a common tec...

This includes a full report of the introduction, method, results discussion etc A volumetric analysis is a chemical analysis involving two different substances. One substance has a known concentration and volume and the other an unknown concentration and known volume. In order to calculate the unknown concentration, the volume of the solution of known concentration is measured. This volume is just sufficient to react with the substance of unknown concentration. This process is called titration. The aim of titration is to find the equivalence point of the reaction.
