Redox

A reaction in which one substance transfers one or more electrons to another substance is called an oxidation–reduction reaction, or redox reaction. Reduction is the gain of one or more electrons by an atom, ion, or molecule while oxidation is the loss of one or more electrons. For example, addition of hydrogen atoms to molecules, or the removal of oxygen atoms, is a reduction while…

Destin Briggs Lu Jack Chem 4235 11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium…

Bio-Rad, Alamar Blue is a “cell viability assay reagent which contains the cell permeable, non-toxic and weakly fluorescent blue indicator dye called resazurin.” (Bio-Rad, n.d.). Meaning that the resazurin is going to be using an oxidation-reduction (REDOX) indicator that will undergo a color change due to the response of the cellular metabolic reduction. “The reduced form resorufin is pink and highly fluorescent, and the intensity of fluorescence produced is proportional to the number of…

Iron reacts to form many colored compounds. It can also displace hydrogen gas from acids as it is a fairly reactive metal. It undergoes exothermic redox reactions. The most common reaction of Iron is its reaction with oxygen to form Iron Oxide which is rust. Another common reaction of Iron is its reaction with sulfur which is a strongly exothermic reaction that produces a charcoal grey substance. It…

The Effect of Citric Acid on Photosynthesis and Cellular Respiration Jacqueline Martinez, Shayla Sanders, Yewande Ifanse, Dyamante Wigenton, Rachelle Hutchinson Biology 1441_045; TA Manish, October 14, 2014 Citric Acid originates from lemons or other fruits in which it is sour in taste. It is said that photosynthesis consumes CO2 when aerobic respiration also known as cellular respiration produces it. Also it states that whenever more carbon dioxide is produced the more acidic the water…

Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

The electrochemical properties of the squaraine dyes (SQ1 & SQ2) were investigated. The effects of the chemical structures of two SQ1&SQ2 dyes were selected in relation to the variable property of -COOH substituent for SQ1 compare to SQ2 which without substituent and determine their potential energy levels in ground and excited states HOMO and LUMO. The HOMO energy levels of the SQ1 & SQ2 dyes are -5.19 eV and -5.16 eV. The LUMO energy levels are calculated to be -3.08 eV and -3.1eV respectively…

blood and MacConkey agar plate will be incubated aerobically. These plates will discover aerobic pathogens if present and used to avoid contamination of the specimen. Cooked meat broth and thioglycollate medium a liquid or semi-solid medium with low redox potential can be used for growth and maintenance of pure culture. Boiling to expel absorbed oxygen should be undertaken before inoculating the cooked meat broth, followed by rapid cooling to 37 degrees Celsius. BACTERIAL MORPHOLOGY AND…

In this experiment, various electrochemical cells were measured and calculated to determine their electrical cell potential. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (0.10 M) │ Cu(s), E cell potential was determined to be 1.040 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (1.0 M) │ Cu(s) E cell potential was determined to be 1.060 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Cu (s)…
