Chloroform

A perfect example actually happened today (refer to date above). I was in lab working with chloroform, brine (water with an extremely high salt concentration), and an unknown reactive product. I needed to separate the product by a simple separation process. After a long St. Patty’s day weekend and a late night of celebration after a Game Cock basketball…

Biological macromolecules are large molecules made up of smaller organic molecules. There are four classes of bio macromolecules : Carbohydrates, proteins, lipids, and nucleic acid. For carbohydrates and proteins these smaller molecules are known as monomers. These similar or identical monomers are covalently bonded together to create a large polymer molecule. Monomers, or base units are bonded together to create larger molecules via dehydration. This involves the removal of a water molecule at…

Two weeks earlier... At first, I can only hear the bumping of tires hitting the asphalt. My vision is completely dark, and my brain can't seem to function properly enough to speak. My recollection of what had occurred in the past few hours seems to slowly be coming back in small snippets at a time. I begin to remember the kiss with Xavier, and coming home, but nothing else. My memory is blank from the moment I had stepped through the front door after it had been jimmied. I try and turn onto…

Log files created by the web browser also store web browsing history information such as web pages visited and accessed along with dates and times of those visits (Ravi, 2007). The registry can provide evidentiary value to the digital forensic investigator as well in relation to web browser artifacts. Items such as passwords, default search provider and search engine, and the URLs typed into the web browser address bar are stored in the NTUSER.DAT file located within the NTUSER.DAT hive in the…

experimentation [16]. Sixteen formulations were prepared according to the experimental design shown in Table 3.Accurately weighed quantities of drug, soya lecithin, and edge activators (surfactant) in various ratios as listed in Table 3 was dissolved in chloroform: methanol (2:1) in 250 ml round bottom flasks. The solvent mixture was evaporated at optimized temperature under reduced pressure at 80 rpm using rotary vacuum film evaporator (Heidolph loborata 4011 digital, Switzerland). After…

Introduction Chlorella vulgaris is known to date back more than 2.5 billion years. C. vulgaris is a unicellular green algae that is eukaryotic (Wells). Because of its long life on earth it has been essential for C. vulgaris to evolve so it can survive. One feature that C. vulgaris has is its ability to grow rapidly. Because of its rapid growth scientist have been studying it and found that it can be used in many different ways; wastewater treatments, production of protein-rich food and feed…

These products are known as disinfection by-products. They include chloroform and are known as trihalomethanes or THMs for short. Studies conducted have shown that tested animals that are exposed to high amounts of THM are at a much greater risk for cancer. Even with humans, long-term exposure to chlorination can greatly…

Moisture determination is important in foods for various reasons including; economic, food quality, microbial stability, labeling requirements etc. this may be done by several methods depending on several factors such as water type, decomposition of other food component among others. One such method of moisture determination is the Karl-Fischer Titration Method (KF). Titration is a technique used to determine the concentration of a known volume of solution. A titrant; that is a solution of known…

absolutely would do it again. I’ve been waiting for the right time to do this, when I was physically, financially, and emotionally ready. It only took a month of part time paycheck to buy the tools I needed: an axe, 12 feet of rope, and a 250 ml of chloroform. Here is what me, a 5 foot 17 girl old, did to the 41 year old man who ruined my life. First, I tracked down his work schedule that was probably the hardest…
