Breathalyzer redox reaction
WebWhen a person exhales into a breath analyzer such as the Breathalyzer™ tube, the exhaled alcohol reacts with compounds in the Breathalyzer™ chamber to produce a change in color from orange to green. The chemical reaction indicated by the color change involves oxidation and reduction. Silver nitrate catalyzes the reaction. 6. http://wwwchem.uwimona.edu.jm/courses/CHEM2402/Crime/Breathalyser.html

WebAug 1, 1995 · Photosynthesis adapts to changes in the level and quality of the illuminating light by redox signalling. For example, an increase in light intensity (right) increases the rate of electron transfer from the photosynthetic reaction centes (PSI and PSII, red). The ‘dark’ reactions that oxidize NADPH with electrons from PSI become rate-limiting ... WebAn oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and …
