Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental

October 17 & October 24‚ 2012 How is Aspirin Made? This lab is about synthesizing aspirin using a hotplate to heat the reaction. It involved vacuum filtration‚ recrystallization‚ and comparing the properties of aspirin with salicylic aspirin. The first thing we did in this lab was make a hot-water bath by putting a beaker with water on a hot plate. After measuring out 2.1 grams of salicylic acid and 3 ml of acetic anhydride‚ we mixed the two together‚ along with 3 drops of sulfuric acid. We

Assessment 2 – Congestive Cardiac Failure 1. Mr Wright’s admission states that he has CCF (congestive cardiac failure). Clearly define CCF. What organs and which body systems are affected by this disorder? Congestive cardiac failure defined Congestive cardiac failure (CCF) is a progressive disease of the heart‚ which involves loss of pumping ability by the heart. Congestive cardiac failure occurs when the myocardium loses its ability to pump enough blood to meet the body’s metabolic needs and is

Centrifugation‚ depth filtration‚ and microfiltration are commonly used. In a recent publication‚ different harvest approaches were investigated for a case study involving recovery of a therapeutic protein from Pichia pastoris fermentation broth.10 |[pic]

contaminated on the way. According to the Community Water Company of Green Valley‚ some bottled waters will occasionally contain microbial contaminants. Also bottled water usually loses a great deal of the natural minerals in water when it goes through the filtration process. Many of those minerals are used by the body to maintain a healthy state. Water is nothing more then a mere rinse if you remove the minerals from the water. It is ironic that bottled water may not be as healthy as most people believe. There

Ultimately‚ through a simple distillation and filtration process‚ crystals of the desired product can be achieved.

cholera and how it spread consisted primarily of morbid poison entering the alimentary canal through means of contaminated water consumption. Snow believed this to be the basis of how cholera was contracted by individuals and believed improper sewage filtration was to blame as well as a means of spreading the disease from person to person. However‚ previous explanations of how cholera was contracted consisted of the theory of airborne infection. This theory proposed that cholera was contracted by inhaling

Extraction and analysis of two compounds from unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119
