Preparation of Sodium Chloride through titration Abstract: acid-base titration is a technique commonly used to determine the moles of acid in a sample by adding a known volume of strong base of a known concentration. The strong base provides the hydroxide ion‚ to react quantitatively with the acid. The point at which the acid is completely and exactly consumed the known quantity of base is called the equivalence end point and is signalled by a colour change in the solution (end point). This colour

than the published melting point of acetaminophen. After conducting a TLC plate‚ the Rf value was calculated to be .4268‚ the same as the standard Rf. Introduction: The purpose of this lab was to identify an analgesic drug and to understand how to interpret infrared spectroscopy. The lab consisted of several steps‚ which include extraction‚ distillation and filtration. Based on the active ingredient crystals that were obtained at the end of filtration‚ the melting point was found. The

Kawasaki disease is a rare disease of childhood. It is the leading cause of acquired heart disease in children. Kawasaki disease causes swelling and inflammation of the walls of the blood vessels. It also affects the mucous membranes‚ lymph nodes‚ and the heart. The heart problems are the most worrisome part of the disease. The inflammation of blood vessels in the arteries of the heart (coronary arteries) can lead to aneurysms. An aneurysm is a weak area in the blood vessel that balloons out. Such

Tenebrio molitor is the scientific name for mealworm. While conducting the experiment‚ the Tenebrio molitor is given a drug name aspirin to see the changes in the worm after taking the drug. The independent variable is aspirin and the dependent variable is death rate. Aspirin is given to Tenebrio molitor to see if they die from taking the drug. In many countries‚ mealworms are being served for meals. It’s surprisingly tasty and is a very high source of protein. Mealworms live in places surrounded

Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group into an acetyl group‚ (R—OH → R—OCOCH3)

Aspirin (ASA) is one of the most commonly used medication in our lives.it is found as analgesic and pain killer in 1899; today‚ it has developed other uses in addition to pain relief‚ such as reduction of inflammation and swelling‚ cancer prevention and treatment for heart attack and stroke. Especially‚ its effect on preventing and treating heart attack has been proven outstanding and efficient. Since aspirin is also an anti-coagulant‚ which means it lubricates the blood and effectively prevents
