Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils. It did great job at pulling stains right out of the cloth. This

their mouths and a happy‚ satisfied grin on their faces. The reason for conducting the research is to know how the colors of our favorite candy-coated sugary rewards came to be and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down

What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying

Distribution of plants at Mer Bleue By Zahra Rao 7690901 BIO1130 Section A6 Demonstrators: Natalia Koud Hong Yew September 22nd‚ 2014 Department of Biology University of Ottawa Hypothesis: The Acer rubrum has adapted to a range of dry habitat conditions‚ which include; the ecotone‚ forest and field. This is because the tree has adaptable roots helping it to cope with differing soil types1. It is most profoundly found in the ecotone because of the moist acidic soil that is found

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or

PLANTS Plants in Our Daily Life A plant(also called green plants) is a multi-cellular living organism‚member of kingdom Plantae.It is at the base of the food web and are Autotrophs.Plants are considered as backbone of all life on Earth and essential resource for living oragnisms.Plants can be reffered as a factory which processes light into energy and manufactures food for it ownself as well as for other living things.Scientists have foundmore than 270‚000 spieces of plants They include a host of

General Conclusion: These experiments helped us understand the importance of molecular polarity. This knowledge can now be used for the future to predict‚ for example‚ if two substances will mix or not. We can now do this by knowing that polar substances only mix with other polar substances‚ while non-polar substances only mix with other non-polar substances. This concept can be used to predict if a substance will be soluble in a specific solvent. The concepts of solubility and conductivity of a

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used
