Hypochlorite

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

higher alkalinity minerals are present. Fiji chlorine levels were double that of tap water. Chlorine is used as a disinfectant to eliminate bacteria and odors. Mastroiann (2011) noted, “In water, the chlorine reacts to form hypochlorous acid and hypochlorites, and could potentially…

Effect of different cleaning products of the growth of K12 strain Escherichia Coli? Which household cleaning product (hydrogen peroxide, Pine-sol, Clorox Bleach, Mr Clean antibacterial liquid cleaner) is the best inhibitor of K12 Escherichia coli (E. coli) growth? The manipulated variable was the cleaning product or disinfectant on used of the Whatman antibiotic assay paper disc. The dependent variable is the zone of inhibition of the prokaryotic bacteria E. coli. In topic one IB requires that…

The first common household item I will discuss is Windex. The company that produces Windex is S.C. Johnson & Son, Inc. from Wisconsin. Although this product is mainly water, other main ingredients include ethanol and isopropyl alcohol. According to Hazard.com, hazards identification for Windex includes a list explaining adverse effects of ingestion or overexposure. Windex should not be inhaled or ingested. It may cause moderate irritation if it’s in contact with an individual’s skin for too…

Chlorine is used as disinfectant as it kills the microorganisms like certain bacteria, but the trouble is that it does not know when to stop killing which will lead to toxic effects for the body. It has also been shown that exposure to chlorine and hypochlorite will lead to dermatitis (Eun et al., 1984). Various researchers have been shown that there is effect of drinking water chlorine on lipid metabolism and thyroid functioning in white carneau pigeon (Revis et al., 1986). When we treat the…

active ingredients of hydrogen peroxide are molecules of oxygen and hydrogen. The mechanism of action for the disinfectant bleach is the destruction of cellular metabolism causing the death of the bacterial cell, its active ingredient is sodium hypochlorite. The final antimicrobial agent is Envirocide which has the active ingredient of isopropanol whose mechanism of action is causing membrane damage, destruction of cellular metabolism and lysis of the…

Equation of trendline 1 calculation: m= rise/run = 12/15 = 0.8 c= 5.9 y= 0.8x + 5.9 Equation of trendline 2 calculation: m= rise/run = 25/45 = 0.5 c= 17.6 y= 0.5x +17.6 Point of intersection: Equate both trendlines to find point of intersection 0.8x + 5.9 = 0.5x + 17.6 x= 39 Since x=39, x2= 9 as x2 represents x in descending order. R2: R2 for trendline 1 = 0.98 Correlation coefficient for trendline 1= 0.96 R2 for trendline 2 = 0.98 Correlation coefficient for trendline 2= -0.99 Ratio…

flask was attached to a ring stand to rest on top of a magnetic stirrer device. In consistent drops, 0.63 mL of glacial acetic was added and the reaction had a pH of 2, which was measured with pH indicator paper. Then, 0.50 mL of 10% w/v sodium hypochlorite (NaOCl) solution was added, and the reagents were reacted for three minutes. Shortly after, 5.13 mL of 10% w/v NaOCl was added incrementally with a Pasteur pipet for about ten minutes. A thermocouple was periodically placed on the outside of…

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease in which there is a loss of motor neurons in the brain and spinal cord, this disease is incurable therefore leading to paralysis and death. The particular two studies discussed will be based on how biomarkers (a tool used by scientist to determine the biological pathways and the progress of the disease) can help find a cure for ALS by creating an effective drug and most importantly early detection. Mice were used as a transgenic…

In a series of trials, treating of DUWLs with sodium hypochlorite, glutaraldehyde, and isopropanol was investigated. These agents reduced microorganisms in effluent water but did not destroy the biofilm matrix in the DUWLs, even with periodic treatments [ 8].Similar results were obtained for Listerine, Bio 2000…
