SMART SOLUTION FOR SOLID WASTE MANAGEMENT ABSTRACT:: when we go arround we notice one annoying thing that is overflowing of garbage bins in public places due to excess disposal of waste which degrades the quality of environment in india.This even leads to bad smell unhygienic conditions for people and also spoils the beauty of environement at tourist places .Eventhough government take measures to overcome this problem but still it is continuing due to irresponsibility

RESULTS Determination of solubility of fenoprofen The solubility data is shown in Table I and it is presented in Figs.1, 2 and 3. The solubility of fenoprofen amongst various oils investigated was found to be highest in oleic acid (198.93±2.91mg/ml) followed by triacetin, labrafil M1944, capryol 90. The solubility of drug was insignificantly different between labrafac lipophil, IPM, and labrafac PG. Amongst surfactants, labrasol showed maximum solubility (129.17±1.4mg/ml) followed by tween 80,

do this, add the water drop-wise to your solid, stirring well between each drop, until the solid just dissolves. You might have to heat the test tube while you are adding the water to keep the solution hot. 4. After getting the solid to dissolve, allow the solution to cool slowly and look for crystals. After the solution has cooled to close to room temperature, cool it in an ice bath. Collect the solid using vacuum filtration and your Hirsh

without losing the solid and successful completion of a series of reactions. This was done through five chemical reactions involving copper. In this lab, elemental copper was put through five different chemical reactions in order to convert it into different compounds. By the end of the fifth reaction, the copper was back to its elemental state. In the first reaction, 0.95 g of pure copper was reacted with 4.0 mL of concentrated nitric acid under the fume hood. The solution was swirled until all

The solid organic compounds that we use in reactions or that come from natural sources tend to have impurities. One way for us to remove these impurities and obtain our desired product is by using a technique called recrystallization. Our goal in this experiment is to prove that recrystallization is a method to purify a solid organic compound with contaminants. In Part A we will purify acetanilide by recrystallization and in Part B we will distinguish the best way to select the solvent required to

This experiment explored the multi-step synthesis of synthesis acetylsalicylic acid commonly known as aspirin. A common procedure used in organic chemistry labs is multi step synthesis. this procedure involves a cascade of reactions that ultimately lead to a desire product. The series of reactions begins with commonly found or readily available reagents which are synthesized into products which can be used for a secondary reaction, and so on and so forth until the final desired product is synthesized

properly to purify multiple organic solids. Recrystallization has become a fundamental technique in organic chemistry and the pharmaceutical industry, for separating and purifying organic compounds. Out of all the techniques used for purifying organic compounds, recrystallization is the most vital one. This is due to its effectiveness, convenience, and industrial applications. Recrystallization has to do with dissolving organic compounds to purify them. The solid acts as the solute as it dissolves

 flashes were  recorded.   The cation  solutions were then disposed of in the  appropriate waste containers.    From   the  information  in  each  of  these tests,  a Cation logic tree was formed  for easy  identification  of  unknown cations.  Part  2:  Anion  Analysis:  The  experiment was  performed on 4  anions: chloride (Cl­), sulfate (SO42­),   nitrate  (NO3­),  and  carbonate  (CO32­).  A  sample  of  each  anion  was  prepared  by placing  10  drops of  each  anion solution into  a centrifuge tube.  

filtration. The reflux apparatus uses a technique involving the condensation of vapors from a reaction mixture and returning the condensate back into the reaction mixture. More simply, the solution is heated allowing a vapor to be produced that in turn is cooled by the reflux condenser and returned to the original solution. This method prevents the solvent from being evaporated off, allowing for maximum product yield. The gravity filtration apparatus is then used in order to remove unwanted contaminants
