Cl 2 (g) + 2 NaOH(aq) → NaCl(aq) + NaClO(aq) + H 2 O. Hence, chlorine is simultaneously reduced and oxidized; this process is known as disproportionation. [citation needed] The process is also used to prepare the pentahydrate NaOCl·5H 2 O for industrial and laboratory use. In a typical process, chlorine gas is added to a 45–48% NaOH solution.
2 NaClO 3 → 2 NaCl + 3 O 2. Potassium and lithium chlorate, and sodium, potassium and lithium perchlorates can also be used in oxygen candles. In the Vika oxygen generator used on some spacecraft, lithium perchlorate is the source of oxygen. At 400 °C (750 °F), it releases 60% of its weight as oxygen: [9] LiClO 4 → LiCl + 2 O 2
A high-pressure sodium street light in Toronto A high-pressure sodium-vapor lamp An HPS lamp that isn't entirely off. A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Two varieties of such lamps exist: low pressure, and high pressure.
An HCL can also be used to tune light sources to a specific atomic transition by making use of the optogalvanic effect, which is a result of direct or indirect photoionization. By shining the light source into the HCL, one can excite or even eject electrons (directly photoionize) from the atoms inside the lamp, so long as the light source ...
2 NaCl + 2 H 2 O → 2 NaOH + H 2 + Cl 2 Without a membrane, the OH − ions produced at the cathode are free to diffuse throughout the electrolyte. As the electrolyte becomes more basic due to the production of OH − , less Cl 2 emerges from the solution as it begins to disproportionate to form chloride and hypochlorite ions at the anode:
Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure product, e.g. for use in the food industry. The reaction can also be triggered by blue ...
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
