Distilled water

leaves of Aloe vera with a length of (55 - 80) cm were selected from the plants and washed with water. The tapering point of the leaf top and the short sharp spines located along the leaf margins were removed by a sharp knife and then the knife was introduced into the mucilage layer below the green rind avoiding the vascular bundles. The top and…

Production of soaps and detergents for oil spill cleanup With another catastrophic oil spill hitting the coast in the last 50 years an environmental group has volunteered to help clean up the spill, specifically to use on affected birds. With environmental concerns in mind, tasked was to create an environmental friendly soap or detergent sufficient enough to clean up the mess left behind. In addition to the creation of soap for the purpose of cleaning, needed was a soap or detergent that would…

result of chemicals being released from human productions, great amounts of sulfur dioxide and nitrogen dioxide are respired into the atmosphere, where rain and gas matter is polluted. Once both sulfur dioxide and nitrogen dioxide come in contact with water or oxygen, acids are formed. Devastation extremes are directly related to the acidic concentration within deposition. High amounts of chemicals in the atmosphere can also result from decaying plants, animals, or natural disasters, such…

the dye extracted from samples of magnetic bentonite clay and of charcoal through filtration. From the data collected in this experiment, it was found that charcoal was a more effective alternative to use as an absorbing agent in rivers to clear the water of harmful PAHs. INTRODUCTION…

hydrogen peroxide affect the rate of reaction, that is represented by the increase in pressure over time? Introduction: Hydrogen peroxide is a chemical compound of hydrogen and oxygen. It is a very strong oxidant but weak in water solution. Hydrogen peroxide decomposes into water and oxygen when heated above about 80°C and also decomposes in the presence of a catalyst. A catalyst is a substance that increases the rate of a chemical reaction but is not changed by the reaction. The catalyst in…

soil and water analyzed kit. The electrode was conditioned with KCl and calibrates with 0.01M KCl solution. The sample…

6. EXPERIMENAL WORK 6.1 Preliminary Work 6.1.1 Collection of Plant material The leaves of Jasminum grandiflorum was collected locally in the month of July locally from Bhopal, Madhya Pradesh, India.

pneumonia. These all bacteria will be culture in the nutrient broth. The first stage is making Nutrient Broth. Weigh out 5.8 grams of nutrient broth powder. Dissolve completely the nutrient broth powder in beaker containing 200 ml of distilled or the deionise water. Then the mixture is transfers to the vials. Those vials are autoclave and sterilise at 1 atmosphere pressure in the temperature of 121 ℃ within 15 minutes. The nutrient Broth vials are inoculate with bacteria. The 200-600 µl of…

Osmosis is the net movement of water towards higher concentration. In osmosis experiment, water likes to diffuse from an area of low-solute concentration to an area of high-solute concentration. The purpose of the osmosis experiment was to observe the diffusion of solutes and the osmosis of water through a semipermeable membrane, which was dialysis tubing. This experiment was done to examine, if the solution is hypertonic, hypotonic or isotonic. The result of this experiment was that…
