Tartaric acid

pathogens and microorganisms may be present in pools that aren’t treated properly and can result in harmful side effects like swimmers ear or diarrhoea. Disinfectants are used to treat pools and chlorine is by far the most commonly used. Hypochlorous acid (HOCl) is the substance that sanitises these swimming pools (De La Matter, 2012). If kept within specified pH parameters then the system works well however there are many stressors of the backyard pool system. This includes variations in pH…

Introduction: Within this task we were required to determine the ecological state of the Reddam House wetland, which I presume is at a good standard. I decided to test the ecological status of the wetland by gathering samples from the wetland and testing it for various aspects in the water and the plants that are found within the area. Method: • Collected water in a sterilized bottle at Reddam House wetland as well as observed surrounding fauna and flora. • Took the water to Rand Water to have…

and even cars (webprojects.edu, 1). Acid rain is something humans should be concerned about in the twenty-first century due to our advancements in technology. The majority of the United States suffer from acid rain and as a result, many communities are impacted making water unsuitable for drinking and the environment around them damaged. Despite the fact that many people think acid rain isn’t a big threat to the world, damages caused by acid rain can be…

Zinc is an important dietary component in human beings and animals. Although not considered hazardous, overdose of Zinc may cause nausea, vomiting, dizziness, colics, fevers and diarrhea and if it exceeds a certain limit it may also prove to be toxic. Zinc, present in natural water in small concentration, most commonly enters the domestic water supply from deterioration of galvanized iron and dezincification of brass[1,2]. Industrial and household waste, discharges directly or indirectly through…

forms the test is positive. The triiodide test requires a visual inspection and if the colors are orange, brown or red the test is positive. The zinc ion test requires the solids to be dissolved in 2-3 mL of water (if a precipitate forms .17 M acetic acid should be added) and then to add 1 magnesium turning. If a fine black solid is deposited on the surface the test is positive. Finally the test for zinc metal requires 3 drops of 3 M HCl solution to be added to the test tube and if hydrogen gas…

Water is the best aid in attaining large, beautiful, and firm breasts. This was a major secret of the ancient Greek beauty queens. And some historical records reveal their simple recipe: dipping the breasts in cold water for five minutes every night. Nowadays, it is scientifically proven that cold water and repeated hot-icy showers are a must for the breast beauty and health. However, professionals claim that a hot water bath also has good effects on the size of breasts. Due to the excessive…

Due to the time restriction,the experiment only once. To make the experiment highly accurate, it should be performed it at least three times, with all the precise measurement of the materials needed, to avoid any kind of error. The control variable would be the solutions; corn syrup and distilled water. The mass of the egg would be tested throughout the experiment. Before placing the egg into the solutions, weigh the mass. After you have the mass recorded, place the eggs into different beakers…

CHM 144M Section C Dr. Zhu Charles Dotse Aileen Decker 8 October 2015 The Quantitative Determination of an Acid in Carbonated Beverages Abstract: The basis of this lab was to juxtapose two different titration methods in their ability to identify the end point, calculate the molarity of citric acid in the two sodas, and apprehend the differences between polyprotic and monoprotic acids. In order to accomplish this, a traditional titration, with phenolphthalein, and a modern titration,…

This chemical reaction involves neutralization, where an acid and base react to produce a neutral solution of salt and water. As this information is provided, the known concentration of NaOH(aq) is 0.25M. It is necessary to rinse out the burette with sodium hydroxide solution before starting titration, as the concentration of the base can be affected by the water used to clean the burette. At the same time, when cleaning the burette it may not have been washed thoroughly . By rinsing with…

Introduction Acid-base titrations are used to calculate properties of an acid or a base by titrating them with a strong Acid or base. In a titration, certain amount of volume of one substance usually a strong acid or base, a titrant, is added to another substance, an acid or base of some kind, until a change in properties are observed. Strong acids and bases are used because they allow the neutralization reaction between the acid and base into salt to go to completion. By titrating an unknown…
