Amanda Anile Course: CHM 101 (E05N)-NVCC Professor: Mihaela Chamberlin Date: 29 April 2017 Experiment Title: Acid-Base Titration Abstract: Vinegar is a common household item containing acetic acid as well as some other chemicals. This experiment is designed to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH. CH3COOH(aq) + NaOH(aq) -> CH3COONa(aq) + H2O(l) By adding the sodium hydroxide‚ which is a basic solution

The town council wants to build a statue that will not be affected by acid rain. In this experiment‚ three different types of rock are used on vinegar (acting as acid rain). The rocks used are marble‚ granite‚ and red sandstone‚ which are the most popular forms of rocks used to build monuments. Each type of rock will be submerged under 20 ml of vinegar in their own separate container. The pH of acid rain around 4.0. Acid rain is caused by a chemical reaction when sulfur dioxide and nitrogen oxide

experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct. Baking soda mixed with vinegar and lemon juice caused the balloon to expand. There was no reaction with the balloon

2017 Introduction The hypothesis is the balloon will be bigger and bigger with the increase of vinegar. The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction. Sodium hydrogen carbonate (baking soda) reacts with ethanoic acid found in vinegar in a 1:1 ratio in the following reaction: baking soda (sodium bicarbonate) + vinegar (acetic acid) --> carbon dioxide + water + sodium ion + acetate ion HC2H3O2 (aq) + NaHCO3 (s) →

April 3‚ 2013 Fake Alert!!! Heinz Apple Cider Vinegar (what are you eating!!!) Hi girls‚ We know many of you girls are using Apple Cider Vinegar for weight loss.It is really hard to find this vinegar in our country.Most of us are buying it from Almas‚Priyo‚CSD‚Gulshan DCC market and from many other superstores.And the only available brand is Heinz.We’ve been using this vinegar for 3months now.Recently we bought a bottle of Heinz Apple Cider Vinegar from Gulshan DCC market.We were really surprised
