samples of vinegar if any had been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere

Vinegar and soap as an Alternative Weed Killer Introduction A. Background of the study Since ancient times‚ vinegar has been used for different purposes like cleaning‚ cooking‚ gardening‚ etc. In gardening‚ it is used as a herbicide. Vinegar is an important element in organic gardening‚ as it has the capability of killing the weeds. Vinegar contains natural acetic acid which helps in destroying the weeds. Acetic acid (systematically named ethanoic acid is an Acetic acid (systematically

Pineapple (Ananas comosus) peeling as a major component in making vinegar to reduce post-harvest loss of pineapple and to promote the safe and positive effects of using pineapple peeling as a major component in making vinegar. This study is helpful to the environment because it reduces pineapple waste which contains residual pulp‚ peels that can cause environmental pollution problems if not utilized. Another is that the vinegar made out of pineapple peelings is natural and less acidic than the

can this be prevented? Does acid rain have effects on not only the environment‚ but the plants and animals that inhabit it? Hypothesis: If vinegar (a substitute for acid rain) is poured over building materials‚ then left to dry‚ the researcher believes that vinegar (acid rain) will cause the building materials to be affected because vinegar (acid rain) has chemicals that are known to destroy many structures in the environment. Variables: Independent variable: building material (marble

keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister - Vinegar - Water - Phone (as timer) - 2 Alka-Seltzer tablets - Electronic scale Procedure: 1. Fill the graduated cylinder with 10ml of vinegar and put it in the clean film canister. 2. Break the Alka-Seltzer tablets to two

Abstract This APA research paper will inform the reader of the monumental court case that The Vegan Lounge believes‚ in some ways‚ is related to their business plan. This case‚ U.S. v. 95 Barrels Alleged Apple Cider Vinegar‚ was chosen because they believe it connects well to a part of their business plan. In the business plan‚ for The Vegan Lounge‚ they have chosen to sell and distribute the sauces they use in their restaurant. These sauces range from hot sauces to barbecue sauces. The case is significant

Aim To find out the difference of reaction time it takes for the baking soda when it meets the vinegar under the condition that the volume of the vinegar changes. Background Information The two reactants‚ which are baking soda and vinegar‚ react with each other. Then it creates product‚ carbon dioxide‚ water and sodium acetate. The chemical name of vinegar is ethanoic acid and baking soda is sodium hydrogen carbonate. To illustrate this phenomenon as a chemical equation‚ it can be shown as C_2 H_4
