CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

Now wash (microscale) the combined extracts with saturated NaCl solution (5mL)‚ then with 10% aqueous potassium carbonate (5mL)‚ then with saturated NaCl solution (5 mL) again. Dry the organic layer with anhydrous sodium sulfate. Decant the organic layer into a small beaker and concentrate to roughly 0.2 mL by evaporation in the hood (do not apply heat!). If the sample goes to dryness‚ re-dissolve in hexane (0.2 mL). *Set aside a small amount of your crude

Importance of Organic Foods The definition of organic agriculture is farming with the use of synthetic chemicals. After World War II‚ larger and increasingly automated farms‚ known as "factory farms‚" put the synthetic fertilizers‚ pesticides and herbicides developed in the 1920s into widespread use. They found that more crops could be produced mass produced. What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health

Leaves into Organic Fertilizer using Earthworms (Lumbricus terrestris) as Agents for Fast Decomposition Chapter I (Introduction) A. Background of the Study Since ancient times‚ farmers have known that adding certain substances to the soil helps produce healthier‚ more abundant crops; such a substance is called fertilizer. The researchers decided to make an organic fertilizer. Organic fertilizers are made up of organic materials such as leaves decay‚ they produce an excellent fertilizer. Fertilizers
