SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

A Warm Welcome “Chuck‚ chuck‚ chuck!” is the sound of the stapler I hear as I walk into Ms. Hernandez’s room. It is around 10:00 am‚ and she has just finished with one of her many meetings for the day. I can see that her room is well-organized; the tables‚ chairs‚ posters‚ name tags‚ ABC charts‚ and all her supplies are in their assigned places. With a smile as big as the state of Florida‚ Ms. Hernandez welcomes me. We pull out two miniature chairs from one of her small tables and

Utopia or Dystopia DNA PROFILING What is this? DNA profiling (also called DNA testing‚ DNA typing‚ or genetic fingerprinting) is a technique that is used to assist in the identification of individuals by their respective DNA profiles. DNA profiles are encrypted sets of letters that reflect a person ’s DNA makeup‚ which can also be used as the person ’s identifier. DNA profiling should not be confused with full genome sequencing. DNA profiling is used in‚ for example‚ parental testing and criminal

Extraction of DNA from an Onion Molecular biologists and biochemists are involved with research in finding out as much as possible about the DNA in plants. DNA was discovered in the 1950’s‚ there still remains a lot to be known about it‚ especially how it is used to determine the physical traits that we all have‚ and how it regulates the workings of the body. deoxyribonucleic acid is a chemical‚ we can do reactions with it just like we can work with any other chemical.

I. Introduction Gone were the days when washing of clothes was considered a burden not only to the person cleaning‚ but also to the environment; this is mainly because of the chemicals in some of these laundry detergents tend to break down the skin’s natural barrier and the water after being rinsed on is already considered useless. Lucky for all of us‚ Victoria Natural Herbal Laundry Powder is here. Its self-proclaimed “Super Cleaning Power” is considered to be gentle and safe. There are four

close to complete extraction are important. If these two elements are not taken into consideration‚ the extraction may not be complete‚ or the extract may contain a large quantity of undesired impurities. The natural fats and oil are mixtures of glycerides of fatty acids. Fats and oils are naturally occurring organic compounds which belong to a large group of water insoluble substances called lipids. Lipids are relatively non-polar molecules‚ they can be pulled out of a sample using relatively non-polar

The main purpose of this lab was to synthesize four soaps and two detergents and determine which one would be the best for an environmental group to use in the event of an oil spill.1 To complete this task‚ five subgoals had to be achieved first. To find the solubility of the fats‚ oils‚ soaps‚ and detergents‚ each of them were placed into different solvents to see if they dissolved. None of the oils and fats were soluble in water (H2O)‚ sodium hydroxide (NaOH)‚ or hydrochloric acid (HCl)‚ but they
