Tartaric acid

water pollution are arising and becoming more frequent from human actions everyday. One example of this is acid rain. Many scientists believe that the recent drop in aquatic life in our bodies of water around the world is owed acidic rain lowering the pH levels. Acid rain produced by coal burning industries flow into all bodies of water after falling on forests, fields, buildings, and roads. The acid rain eventually raises pH levels of surrounding bodies of water leading to it 's many negative…

reaction and see how different properties - such as concentration and temperature - affect the reaction rate. This was to enhance understanding and gain knowledge of how certain properties affect reaction mechanisms and activation energies, and how acid-base equilibria behaves. The data generally supported the hypothesis. It can be clearly seen that higher molarities of t-BuCl gave faster reaction rates, and it is an even clearer trend between the temperature of the system and the reaction…

Is Perrier Bad for You? Perrier is carbonated bottled mineral water sourced from the Les Bouillens spring in Southern France. Although the water from the spring is already naturally carbonized, carbonic gas is added to it again as it is bottled. Because of the many health benefits this water promises, it became very popular among Americans who wanted to lead a healthy and active lifestyle. Perrier soon became a widely-used substitute for soft drinks or cocktails and has gained a reputation for…

Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch. August 2015 ABSTRACT Malolactic fermentation is the conversion of harsh and acidic malic acid to a more desirable form of lactic acid in wine by Lactic acid bacteria, after the completion of alcoholic fermentation. This reaction can take place naturally in wine, proving to be very unpredictable and not always favourable, or by inoculation with bacterial cultures.…

Introduction: DNP and research question The organic compound 2,4-dinitrophenol (DNP) is a crystalline solid with the molecular formula C6H4N2O5. The molecule is soluble in water to some extent and is fully soluble in sodium and potassium hydroxide solutions. The compound can also be explosive. It is usually used in dye, weed killers, wood preserver, photographic development among other things and it has even been used as a weight loss agent. In fact, it has been claimed to be the king of the…

milk is mixed with sulphuric acid and iso-amyl alcohol in a special Gerber tube, permitting dissolution of the protein and release of fat. The tubes are centrifuged and the fat rising into the calibrated part of the tube is measured as a percentage of the fat content of the milk sample. Apparatus: - Butyro meter, 10.75ml pipette,amyl alcohol, stoppers, gerber centrifuge, water bath. Reagents:-Sulphuric acid, amyl alcohol. Procedure:-  Transfer 10 ml of sulphuric acid in to butyro meter .  Warm…

four the acid rain and tap water seeds were alike. The seeds were round and tan. On day two the seed coat became squishy. On day three test one seeds two and three of the acid rain and water began to sprout roots, and all of the seeds in test two and three began to sprout. Seeds one, two, and three in the acid rain test one group’s roots began to curl on day four and the stem was just barely visible in seed one. The water seeds in test one, two and three the stem became visible. The acid rain…

Eggsperiment Purpose Is an egg similar to a human cell? Hypothesis If the egg is put in milk, then the shell will grow back. According to Mama Natural, “High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.” Also, according to My Plastic Free Life, “eggshell powder contains roughly 400 milligrams of calcium per gram.” Since the milk I use, 2% Fat, has 295 milligrams in one cup…

Pimples abide approaching to dead skin cells naturally produces oil in excess skin blocking pores. A common misconception about blackheads is that they are caused by dirt. Blackheads are created if the pores are open and clogged pores until it turns into a black color as the air hits the open, clogged pores. Washing your face or force several times not one day gets rid of blackheads. If anything, that will dries out your skin and cause irritation. It will also cause more oil to be produced,…

Background: Isopods, or what are often called pill bugs, are crustaceans. Isopods live in damp environments. They can be found under rocks, logs and in soil. In this lab, 10 isopods were given a choice between salt water or regular water chambers to test their preference. The results were recorded every 30 seconds over a period of 10 minutes. Problem: It is known that isopods have a preference for moisture.This lab will specifically test whether or not an additive will affect a pill bug's…
