Calculation of Acetic Acid Percentage Composition in Solution

Introduction

Acetic acid is a key component in vinegar, which is commonly used in various culinary and household applications. Understanding the percentage composition of acetic acid in a solution is important for many scientific and practical purposes. In this case, we will calculate the percentage composition of acetic acid in a solution based on a given experimental setup involving titration.

Experimental Data

10mL of vinegar was diluted with 50mL of water to create a solution. Next, 25mL of this solution was titrated with 0.1M NaOH. It was found that 45mL of the NaOH solution was needed to reach the end point of the titration.

Calculation

Final answer: The percentage composition of acetic acid in the original solution can be calculated using stoichiometry and the formula for percentage composition. Based on the calculations, the estimated percentage of acetic acid in the original solution is 27%.

Explanation

To solve this problem, we first consider the basic formula for percentage composition: (partial mass/total mass)*100%. Using the given information and the stoichiometry of the reaction between acetic acid and NaOH, we determine that the percentage composition of acetic acid in the original solution is around 27%, based on the mass of acetic acid and the initial mass of the solution.

10mL of vinegar was diluted with 50mL of water, 25mL of the solution was titrated with 0.1M NaOH, and 45mL of NaOH was needed to reach the end point. What is the percentage composition of acetic acid in the original solution? The percentage composition of acetic acid in the original solution can be calculated using stoichiometry and the formula for percentage composition. We find that the amount of acetic acid is the same as the amount of NaOH used in titration, which helps us obtain a value in grams. This mass, when used in the formula, gives an estimated percentage of 27% for the acetic acid composition.
