Waste Disposal Metal Ions
709 wordsQualitative Analysis of The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is done. Also, identificat...

Distilled Water Color Change
1,564 wordsA theme Carbohydrates INTRODUCTION A theme that we have seen and studied in this class is that a particular form or structure of a molecule plays a significant role in the function of that molecule. Since we are interested in the function of molecules. it helps to study their structure. One of the major classes of organic compounds found in cells are carbohydrates. These carbohydrate are made of carbon, hydrogen, and oxygen in a ratio of 1: 2: 1 respectively with a general formula of X (CH 2 O) ...

Coca De Mat Rats Or Monkeys Cocaine
851 words&# 61623; Crack Coke Facts Crack &# 61623; Crack is actually a less pure sort of free-base cocaine. Unlike old-fashioned free-base, however, its production doesnt involve any flammable solvents. &# 61623; Crack is usually made by mixing two parts of cocaine hydrochloride with one part baking soda in about 20 ml of water. The solution is then heated gently until white precipitate form. Heating is halted when precipitation stops. The precipitate is filtered and retained. The precipitate may then b...

Peptide Bonds Test Tube
606 wordsThis lab used many test to determine which functional groups were present in certain substance. The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reduce the Caprice ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when at low levels. In both the onion juice and glucose solution the reducing sugar levels were very high, because the test came back dark oran...

Test Tube First Four
2,315 wordsIntroduction: Qualitative Qualitative Analysis Qualitative Analysis Introduction: Qualitative analysis is used in the determination of the identity of a substance. It is different from quantitative analysis, which deals with the determination of the amount of a substance. In this experiment, qualitative analysis techniques are used to determine whether or not a sample contains a certain ion. When using this method, an unknown and a reactant are mixed. The result of the reaction leads to a conclu...
