Sodium hypochlorite

because it is commonly referred to as highly toxic and lethal. We wanted to know more about its chemical makeup to better understand the dangers that come while using Clorox bleach. History: The active ingredient in household bleach is Sodium hypochlorite, and it was discovered by the French chemist Berthollet, in Javel on the outside of Paris, in 1787. He discovered that this chemical had the ability to whiten material quickly and put the product to commercial use in 1914 with great success

iodide ions, Bromine will displace iodide ions but not chloride ions, and Iodine will not displace either bromide or chloride ions from the solution due to the order of their reactivity. Materials: (A list of all the materials you will use) Sodium Hypochlorite Potassium iodide solution (1 mol/litre) Bromine water (1 mol/litre) Cyclohexane Iodine-potassium iodide solution (dissolve 20g of KI and

LAB 1 – THE SCIENTIFIC METHOD *Adapted from LabPaq CK-GCC Purpose: The purpose of this experiment is to learn about and use the Scientific Method. The discussion of physical properties such as density, color, texture, smell, and solubility will take place. Observations and Experimental Data: Table 1: Making Observations Procedure Observation A. Torn paper Vertical tear: easier to tear, more visible fibers, more jagged edges and uneven tear. Horizontal tear: harder to tear,

pools in either a gaseous or as sodium or calcium hypochlorite. The chlorine is added to water to help prevent people from getting sick from disease-producing microorganisms. The chlorine that is added and reacts with the organic material and metals in the water is the chlorine demand for the water as it will not be available for any disinfection that keeps people from getting sick while in the pool. The residual test is

treatments. Sodium hypochlorite may be corrosive to some instruments, such as gold-plated instruments. Before instruments are immersed in sodium hypochlorite, the instrument manufacturer should be consulted about the instrument's tolerance of exposure to sodium hypochlorite. Instruments should be decontaminated by a combination of the chemical and recommended autoclaving methods before subjecting them to cleaning in a washer cycle and routine sterilization. 1. Immerse in a pan containing 1N sodium hydroxide

1. Sodium Iodide is not an electrophilic source for Iodine because Iodine is the least reactive of all the halogens, and it itself does not serve as a base, due to its positive charge. This means that Sodium Iodide needs an Oxidizing agent to make it a strong electrophile. 2. Sodium Hypochlorite is an oxidizing agent for Sodium Iodide, which in turn contributes a strong, electrophilic Iodide atom to the aromatic ring in the final product. The mixture was orange/red, indicating the two substances

Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all

In many ways, any living being is the product of water. The figures are relevant for this assumption: the human body contains 60% water. A newborn has at birth 64% water in his organism while the fetus in the third month of pregnancy has in his tissues, 91% water. As a man ages he starts to dry: around the age of 70, the body contains 46% water. The body is composed of 25% solids and 75% liquid material in which the solvent is water. Furthermore, even the brain tissue is composed of 85% water (Wedro
