  • Investigating The Mass Rate Of Sodium Hypochlorite

    751 Words  | 4 Pages

    INTRODUCTION: The purpose of this two-part experiment was to “determine the mass percent of sodium hypochlorite in a commercial chlorine bleach sample” (lab website). Titration is used in this lab twice. In Part one, students will use the solution of KIO3 primary standard and use this solution to standardize a solution containing sodium thiosulfate. When the KI is added to the solution, it forms a brown/yellow color. Then students used titration to add Na2SO3 to make the color go from brown/yellow

  • Advantages And Disadvantages Of Contaminated Dental Disinfect

    1495 Words  | 6 Pages

    -Contaminated dental impression will result in a contaminated dental cast. Because of potential damage to the model, it is more difficult to disinfect a cast than to disinfect an impression. - There is ample documentation of the transfer of microorganisms onto and into impressions. Organisms can also move into dental casts. Some of these organisms can remain viable for up to 7 days. Therefore, it is preferable to disinfect the impression prior to the fabrication of a cast. (10) Dental impressions

  • Chlorine Is The Single Largest Contributor For Safe Drinking Water

    1296 Words  | 6 Pages

    INTRODUCTION Chlorine is the single largest contributor to safe drinking water, in the history of public health. In 1902 the first chlorine disinfection system was installed in Belgium. By the 1920’s nearly the whole world started using the process. Due to this disinfection process many disease-causing microorganisms were abolished. According to Life Magazine (1997) “The filtration of drinking water plus the use of chlorine is probably the most significant public health advancement of the millennium”

    Determination of the Rate Law for the Bleaching of Blue One Objective The objective of this investigation is to determine how the concentrations of the reagents in the reaction between Blue One dye and Sodium Hypochlorite (bleach) will affect the rate for the reaction. This will be done by through the determination of the rate law with respect to the orders of reaction for the reagents as well as the overall order of the reaction. Introduction The question for this investigation came about when

  • The Health Effects of Chlorinated Drinking Water Essay

    NaOCI- in the bleach inside Janola. Introduction: The active ingredient in most chlorine bleaches is sodium hypochlorite, NaOCl. The oxidizing action of hypochlorite ion, OCl-, kills germs and also decolorizes many stains and dyes. I will determine the concentration of the active ingredient in household bleach; Hypochlorite Ion (OCI-). I will do this using a titrimetric analysis in which the hypochlorite is treated with Iodide (I-) resulting in the production of (elemental) Iodine (I2). This is then

  • Essay on Chem 2c Post Lab

    that the effective analytical connection for analysis of hypochlorite anion by the thiosulfate anion in this experiment is the sum of the two reactions: 1) hypochlorite anion with iodide anion to form iodine, and 2) thiosulfate anion with the iodine formed in reaction one. In your laboratory notebook sum these two reactions to find the stoichiometric factor that relates moles of thiosulfate anion needed to react with each mole of hypochlorite anion in the bleach sample. Then select the correct

  • Oxidation Of 2-Octanol Lab Report

    Oxidation of 2-Octanol Oxidation of 2-Octanol Using Hypochlorite as an Oxidizing Agent Jessica Johnson CHEM 331L-002 15 November 2017 – 29 November 2017 Abstract The purpose of the experiment is to oxidize a secondary alcohol (2-octanol) by using sodium hypochlorite (bleach) to produce 2-octanone. The starting material consisted of a sample of 2-octanol that was placed into a three-neck flask along with acetic acid and acetone creating an acidic solution. While monitoring temperature fluctuations

  • Effects Of Propylene Glycol On Organ System Toxicity

    toxicity. There are concerns that Propylene Glycol can cause brain, liver, and kidney abnormalities. The chemicals that Clorox bleach contains are water, sodium hypochlorite, sodium chloride, coco-betaine, fragrance, sodium carbonate, sodium chlorate, sodium hydroxide, sodium [olyacrylate, and sodium xylene sulfonate. Sodium hypochlorite has several short term potential health risks such as causing irritation and burns when in contact with skin, causing eye damage and irritation when in contact
