Redox

Copper also gains a net charge of +2, so the reaction was a redox and also a gas-forming reaction. After the 4 mL of nitric acid was added to the .2511g of copper in the beaker, the copper metal effervesced and began to break down; eventually, it dissolved into solution as ions. A brown gas was observed forming in…

concentration of aqueous 〖"NaHCO" 〗_"3 " Levels of Independent Variable: 0.10 M 〖"NaHCO" 〗_"3 " , 0.50 M 〖"NaHCO" 〗_"3 " , 1.0 M 〖"NaHCO" 〗_("3" ) , 1.5 M 〖"NaHCO" 〗_"3 " , and 2.0 M 〖"NaHCO" 〗_("3" ) Dependent Variable: The average rate of the redox reaction Controlled Variables: Temperature of the solution to maintain reaction rate Hypothesis: If different concentrations of aqueous 〖"NaHCO" 〗_"3 " are tested, then a 2.0 M concentration of 〖"NaHCO" 〗_"3 " will reduce the tarnish on…

experiment such as the reaction of Sodium Thiosulfate and Hydrochloric Acid includes the “Yellow Snowstorm” reaction – a reaction between Copper (II) and Thiosulfate. Copper (II) sulfate [CuSO4·5H2O] dissolves to give cupric ion (Cu2+); in the context of a redox reaction with thiosulfate, the cupric ion acts as an oxidizing agent. Reactions within the temperature on Sodium Thiosulfate and Hydrochloric Acid occur as the result of molecules interacting with each other to create new substances.…

Lab report Questions What will happen when zinc is placed in copper (II) sulfate? What will happen when copper is placed in copper (II) sulfate? Prediction It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation. The prediction about the copper (II) sulfate and copper is that nothing will happen. Hypothesis It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the…

Owing to the “Grey Tsunami” happened in UK throughout the decades, which is mainly characterised by the remarkable change in human age structure and the increased proportion of the aged population, ageing-related studies have been extensively conducted and gained a lot of interests to investigate the factors that affect the human health trajectories. Ageing process was once described as “an unsolved problem in biology” by Medawar, but nowadays, collectively data from various sources proved that…

hydrogen. While in terms of electron transfer, reduction is gains of electrons. When the process involved the reduction reaction, there was always being oxidation takes place in the reaction. This is because both reduction and oxidation were known as a redox reaction, where both of the reactions are going on side-by-side. Vice versa, oxidation is gain oxygen, loss of hydrogen and loss of electrons. (Clark, 2013) In order to complete the oxidation-reduction reaction, they need some substance…

In this lab we compared fermentation rates under various conditions also known as anaerobic and cellular respiration with an aerobic process. Cellular respiration, is the method when food molecules are broken down from glucose to energy molecules known as ATP. As stated in lab manual BSC 2010L the equation formula is C_6 H_12 O_6+ 6O_2→6CO_2+6H_2 O+energy (including~ 36 ATP) (Upadhyaya, 2018). Fermentation, similar to cell respiration begins with glycolysis; it is the breakdown of glucose with…

There is a variety of amino acid residues that take part in covalent binding of flavin coenzymes to enzymes.The ribitol moiety does not take part in the redox function of flavin coenzymes. The stereochemistry and nature of the sugar alcohol, both are considered important. Some riboflavin analogs are partially active and most are inactive or having antivitamin activity, but in microbiological assays they…

Cellular respiration is the process of “breaking down organic molecules to release their stored energy” usually using glucose, and convert it into ATP through an aerobic process. (Upadhyay 2018) Cellular fermentation is also a part of cellular respiration, but it is an anaerobic process which means it does not require oxygen. There are two discussed types of fermentation: Alcohol Fermentation in which “glycolysis converts glucose in to pyruvate, producing NADH and FADH2, then pyruvate is broken…
