understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the bottom edge and evenly spaced out. Each

Research Paper chromatography uses selective adsorption on a strip of paper. It is used for separating and identifying mixtures that are or can be colored‚ especially pigments. This can also be used in secondary or primary colors in ink experiments. Is it used for Contaminants in rainwater‚ Analysis of narcotics‚ and Detection of substances in urine. Purpose • The purpose of this lab is to see the separation of dye on the candy. Data and Observations Marker Color Prediction - Alcohol Prediction

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

TOPIC Risk management with respect to Oil & Gas Industry INTRODUCTION India is the fifth largest consumer of energy in the world‚ and is likely to surpass Japan and Russia to become the world’s third biggest energy consumer by 2030. According to the International Energy Agency (IEA)‚ hydrocarbons satisfy major energy demand in India wherein coal and oil‚ together‚ represent about two-thirds of total energy use. Natural gas accounts for about 7 per cent share. India has about 5.7 billion barrels

Analysts expect gas prices to decrease or remain mostly flat not only in 2014‚ but for years to come. Nonetheless‚ drivers in some states will see higher prices at the pump‚ starting January 1. Gas prices may not have seemed all that cheap in 2013. But in fact‚ prices for the year as a whole were less expensive than they have been. According toAAA’s year-end report‚ American drivers paid $3.49 per gallon of regular‚ on average for 2013. That’s the cheapest per-gallon average since 2010; the national

Marijuana and Alcohol: Effects on the Body It shouldn’t be much of a surprise that alcohol and marijuana comprise the two most commonly abused drugs by young adults in America. But while many would ask why young adults use these drugs‚ it’s more important to understand how these drugs affect the body. What exactly do these drugs do to the body and how does the body process them? Are the effects always negative? Does the amount consumed make a significant difference? First I will give a brief history

Soda Ash Analysis and Volumetric Analysis of a Carbonate-Bicarbonate Mixture De Guzman‚ Danica Justine R. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila Abstract Titration is a laboratory method in which the endpoint of a reaction is determined quantitatively. In this experiment‚ the amount of soda ash present in a sample was determined and the alkalinity reported as it was titrated using HCl as the titrant. Also‚ the percentage

Chromatography Analysis of Black Pens to Determine Unknown Sample Purpose: Paper chromatography was performed on five different black pens‚ using four different solutions to determine which would be most appropriate to use on an unknown sample. Paper chromatography was then performed on the unknown sample to identify which pen was used to create it.
