amounts of glucose‚ amino acids‚ urea‚ and salts in urine. To test this we used different chemicals that would react with one of the four items above showing either a high concentration or low concentration within the urine. By using a solution called silver nitrate we could test whether or not salt was present in the urine. If the urine turned a cloudy white after adding the silver nitrate the urine had a high concentration of salt. To test for amino acid we used a chemical called biuret solution. If

The presence of carbohydrates in a solution can be determined by a qualitative test of Molisch test. Molisch test is a general‚ sensitive chemical test and positive for all kinds of carbohydrates which in free form or in combined form. The test is based on the dehydration of the carbohydrate by concentrated sulfuric acid to produce an aldehyde which condenses with two molecules of phenol‚ resulting in a coloured compound. Molisch reagent is a solution of α-napthol in 95% ethanol. The aldehydes produced

aldehydes are known as aldoses. Sugars that are ketones are known as ketoses.Glucose and galactose are example of aldoses while fructose is an example of ketoses.There are few test can be done for testing these sugar to show or prove are they reducing sugar or non reducing sugar.Example of the test that can be done is Benedict test. 1 In plant‚glucose is stored as the polysaccharide starch.Example of food that rich in starch is oat‚cereal‚rice and corn.Starch can be divided into

From this‚ we can generally see how the data from each group is spread out across each ligation condition. Table 2. ANOVA test results. The p-value corresponding to the F-statistic is lower than 0.05‚ suggesting that one or more treatments are significantly different. We can see that the treatments that are significantly different are the 1:1 with stuffer and 2:1 without stuffer

UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

The Charpy impact test‚ also known as the Charpy V-notch test‚ is a high strain-rate test which determines the amount of energy absorbed by a material during fracture. The Charpy test specimens were made according to the dimensions of standard ASTM A370. One of the main reasons for concern for natural composites laminates generally is the low values

Determination of Water Hardness Using a Titrator Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains

10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus
