acid in a sample of vinegar? Prediction: The manufacture of claims on the label that the vinegar contains 5.0% acetic acid‚ which translates into a 0.87 mol/L concentration of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one solution to another until chemically equivalent amounts react. Vinegar is a solution of a

Titration Analysis of Vinegar Student: Araik Movessian Grade: 12 Course: SCH4U Teacher: Tijana Knezovic Purpose and Introduction: In this experiment the question of “what is the molar concentration of acetic acid in a sample of vinegar?” was answered via titration using a standard solution of sodium hydroxide‚ NaOH(aq). In this investigation‚ students are to act as quality control chemists. Their purpose is to test the acetic acid concentration of the vinegar to discover whether it

Objective Determine the concentration of acetic acid of vinegar‚ in terms of (m/m). Introduction Neutralization is a reaction of an acid with a bases to produce a salt and water. For example‚ the reaction of the strong acid HCl with the strong base NaOH produces the salt sodium chloride and water HCl(aq) NaOH(aq) ( NaCl(aq) H2O(l) Since the acid‚ base‚ and salt in this reaction are all strong electrolytes‚ the net ionic equation for this reaction is H(aq) OH-(aq) ( H2O(l) This same result

Science Assignment 1.1 Introduction Vinegar was discovered around 5000 BC and it is documented to have been used by Hippocrates who has used vinegar as a medicine for wounds. Vinegar has many uses‚ although the main use for vinegar has been for treatment of wounds. It is also been commonly used as a cleaning agent throughout the years‚ even to this day. Vinegar is often used in cooking‚ especially salads. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1785201/ Neutralisation (in science) is to

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator

Science C.A.T Year 9 2014 Advanced by Sara Hamilton 9H Testing Vinegar – Acid Base Titration Aim The aim of this practical experiment was to pair up and measure the concentration of the acid in three different brands of vinegar. We added a base liquid‚ to the three different brands of vinegar until a neutralization reaction occurred. We conducted the experiment using the titration method. Hypothesis My hypothesis is that the vinegar that will have the highest acidic level will be Cornwell’s because

Experiment 9 and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution‚ volumetric analysis was used. In volumetric analysis‚ a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4

INTRODUCTION Differences between acids and bases An acid-base reaction is based on the reaction involving the ionization of water H2O -> H+ + OH- This means that water can break apart into a hydrogen ion and a hydroxide ion. These two ions can also join together to form a water molecule. When a strong acid is placed in water‚ it will ionize completely‚ and break down into its constituent ions in which one of it a hydrogen ion. When a strong base is placed in water‚ it will ionize
