encompasses 7‚107 islands‚ though only about 2‚000 islands are currently inhabited. With a rapidly growing population and lack of adequate disposal sites‚ solid waste has become a major problem for most medium to large – size cities. When Philippine President Gloria Macapagal – Arroyo took office in January 2001‚ the first act she signed into law dealt with solid waste management systems have posed serious health risk particularly in densely populated areas. In Manila‚ for example‚ the closure of the largest

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co

Synthesis and Purification of Acetylsalicylic Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions‚ creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride‚ acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly‚ an excess of methanol will form methyl salicylate‚ which is also an analgesic. In this experiment‚ we shall use

Lab 3 – Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The

DNA extraction and purification is an essential tool in understanding the biological basis and significance of a eukaryotic cell. Its role is pivotal to numerous scientific applications ranging from basic science research to applied research. Hence‚ DNA is found in all living organisms. Fragaria x ananassa‚ also known as a strawberry has been widely used as one of the many biological models in studying DNA structures due to its accessibility. Strawberries are octoploid which contain large genomes

ABSTRACT Solid Waste Management is an area that is drawing a lot of attention in urban areas. It is acknowledged that while the problem is acute‚ the financial support is inadequate. This project was conceptualized to demonstrate what could be done with waste generated locally‚ with minimal investments. This pilot plant is expected to provide significant impetus to the eco-friendly initiatives in the institution. The input to the system comes from the food waste that gets generated

SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement. Suspended solids refer

Ingredients of the Melting Pot When reflecting on a timeline of America‚ what is clear is that this nation has grown in many ways due to far-reaching ideas‚ movements‚ and historical events. Immigrants who decided to continue their lives in the United States remain as the key factor of keeping this country functioning at the prosperous rate that it is. Unfortunately‚ Immigration has always been a controversial matter in America. Nonetheless‚ the population of the United States’ composes of citizens

the Experiment: The intention of the experiment is to use solvent extraction methods to separate a mixture containing a carboxylic acid and a neutral compound. Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving of

acetic acid. Boil mixture for 30 minutes. Add the phenylhydrazine solution through the condenser. Remove from the hot plate. Rinse with 5 mL of 1:1 mixture of water and glacial acetic acid to complete the transfer of phenylhydrazine. When a yellow solid emerges‚ swirl the mixture. Wrap a dry cloth around the flask. Cool to room temperature (preferably overnight). Filter off osazone. Press and drain it. Wash with a cold mixture of 10 mL each of water and ethanol. No need to dry the product for the
