Hypochlorite

In everyday life, people use antibacterial products to sanitize their homes. Some of the common active ingredients in household cleaning products are thymol, lactic acid, sodium hypochlorite, and ethanol (e.g. active ingredient in some hand sanitizers). The purpose of our experiment was to determine if antibacterial products lost effectiveness in killing common bacteria in everyday environments after repeated use. This is an important environmental issue because if these products are losing…

investigating the stereoselectivity of different reducing agents. During the first week, 4-tert-butylcyclohexanol, a secondary alcohol (mixture of cis and trans stereoisomers) is to be oxidized into a ketone, 4-tert-butylcyclohexanone using sodium hypochlorite (bleach). Thin layer chromatography (TLC) is used to monitor the progress of the the reaction. The second week of the reaction, 4-tert-butylcyclohexanone is reduced using sodium borohydride or the Meerwein-Pondorff-Verley (MPV)…

of 9-fluorenol, which is the decrease of a molecule’s hydrogen content.6 The following chemicals were used in the experiment: 9-fluorenol, sodium hypochlorite (the oxidizing agent), sodium thiosulfate (the reducing agent), sodium bicarbonate, acetic acid, and acetone.3,6 To begin the experiment 9-fluorenol, acetone, acetic acid, and sodium hypochlorite were added in sulfate is added to remove excess water from the hexane layer that is collected using the separatory funnel.6 To determine the…

Oxidation occurs when an element loses electrons and reduction occurs when an element gains electrons. Oxidation and Reduction are processes that always work together, hence the term oxidation-reduction reaction or redox reaction. Oxidation is also the gain of oxygen and loss of hydrogen while reduction is the loss of oxygen and gain of hydrogen. Redox reactions occur in everyday life, it is a highly significant form of chemical reaction. Examples of real life redox reactions include: combustion…

Scientists use a scale to measure how acidic or basic a liquid is. That scale is called a pH scale. The pH scale is a number from zero to fourteen. Accordingly, zero to seven liquids are considered acid. However, seven is considered a neutral, like distilled water. Therefore, eight to fourteen the liquids are considered basic. For instance, a pH of two is going to be an acidic liquid. Thus, a pH of twelve would be measured as a basic liquid. Additionally, a strip of litmus paper will…

commercial bleach with trade name XXX was used and contains XXX g L-1NaOCl (equivalent to 4% w/v available chlorine at the time of manufacture), and XXX g L-1sodium hydroxide (NaOH). Chemicals used for feather treatment were 15% sodium hypochlorite, ethanol absolute, methanol, ether, 30% hydrogen peroxide, Cationic Surfactant, and n-hexane supplied by xxx. Sodium hydroxide pellets, and sodium dodecyl sulphate powder were supplied by xxx. Equipment Equipment used in this study is…

The purpose of this report is determine whether the natural product; vinegar, is better than man made chemical products; Domestos and Pine O clean. This will be determined by the results of the experiment which product has created the largest zone of inhibition. To determine which of the three disinfectants are the most effective depend the one with the largest inhibition zone. Bacteria are tiny microorganisms that colonise together and are found in every living organism. Bacteria is a type of…

the industry raises the question, “Should water chlorination be banned?” When chlorine is added to water (H2O), hypochlorous acid (HOCl) and/or hypochlorite anions (OCl-) are formed. The combination of these creates free chlorine, the most effective chlorine based disinfectant. Common chlorinating products include chlorine gas (Cl2) and calcium hypochlorite [Ca(OCl)2]. The water treatment process often consists of screening, coagulation, settling, filtering, and disinfection (How is Water…

Introduction The Jackson Pike Wastewater Treatment Plant, located in Columbus Ohio, along with the Southerly Plant are responsible for treating a combined average of 208 million gallons of water per day [1]. Founded in 1937, the Jackson Pike Plant first treated approximately 50 million gallons of water per day. To keep up with a growing Columbus population, the wastewater plant has been upgraded to treat 150 million gallons per day. On September 7th, 2017 Carnell Felton, the plant’s assistant…
