Sodium hypochlorite

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…

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…

the features of bacteria constantly changing, there are theories about how they affect the growth of bacteria. Firstly, bleach is a disinfectant which is effective in killing bacteria due to the active ingredient sodium hypochlorite. There are theories which suggest that sodium hypochlorite has power as an oxidizing agent and when in contact with bacteria, fully oxidizes the cells of the germs and kills them (Sandoval,…

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…

good things about it too! Calcium chlorate is produced on an industrial scale. It is produced by the chlorination of milk of lime. It is produced by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionates when heated with excess chlorine to give calcium chlorate and calcium chloride: 6Ca (OH)2 + 6 Cl2 → Ca(ClO3)2 + 5 CaCl2 + 6H2O. “The big problem with making calcium chlorate is the buildup of calcium hydroxide on 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…

According to the PubChem (2017) household bleach has a chemical formula of NaOCl meaning one atom each of sodium, oxygen, and chlorine with the chemical name of sodium hypochlorite, whereas ammonia’s chemical name is azane and the chemical formula is NH3, meaning one atom of nitrogen and three atoms of hydrogen, and when combined, the reaction of 2(parts) NaOCl + 2NH3 → 2NaONH3 + Cl2 takes place…

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…

INTRODUCTION: According to Ong andHho1 fournier’s gangrene was originally described by Baurienne in 1764, but named by jean Alfred Fournier(1832 - 1914) in 1883 when he described the occurrence of a condition characterised by sudden onset in previously healthy young men, rapid progression to gangrene and absence of a definite cause, as quoted by Stephens et al.2 and Laor et al.3 the Persian physician Avicenna (980 - 1037) had earlier described the same condition in his book the Canon 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…
