Hydrofluoric acid is fluoride prozac a solution of hydrogen fluoride (HF) in water. It is a precursor to almost all fluorine compounds, including pharmaceuticals such as fluoxetine (Prozac diverse materials such as, pTFE (Teflon and elemental fluorine itself. It is a colourless solution that is highly corrosive, capable of dissolving many 80 mg of prozac of prozac">80 mg of prozac href="http://joeckellaw.com/natural-replacement-for-prozac/" title="80 mg of prozac">80 mg of prozac materials, especially oxides. Its ability to dissolve glass has been known since the 17th 80 mg of prozac century, even before. Carl Wilhelm Scheele prepared it in large quantities in 1771. 3, because of its high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric acid is usually stored in plastic containers (although ptfe is slightly permeable to it). 4, hydrogen fluoride gas is an acute poison that may immediately and permanently damage lungs and the corneas of the eyes. Aqueous hydrofluoric acid is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death. By interfering with body calcium metabolism, the concentrated acid may also cause systemic toxicity and eventual cardiac arrest and fatality, after contact with as little as 160 cm2 (25 square inches) of skin. Contents, acidity edit, hydrofluoric acid is classified as a weak acid because of its lower dissociation constant compared to the strong acids. It ionizes in aqueous solutions in a similar fashion to other common fluoride prozac acids: 5, hF H2O H3O F, hF is the only hydrohalic acid that is not considered a strong acid,.e. It does not fully ionize in dilute aqueous solutions. When the concentration of HF approaches 100, the acidity increases dramatically because of homoassociation : 3 HF H2F FHF. The bifluoride (FHF) anion is stabilized by 80 mg of prozac the very strong hydrogenfluorine- hydrogen bond. 6 Production edit Hydrofluoric acid is produced by treatment of the mineral fluorite (CaF2) with concentrated sulfuric acid. When combined at 265 C, these two substances react to produce hydrogen fluoride and calcium sulfate according to the following chemical equation : CaF2 H2SO4 2 HF CaSO4 Although bulk fluorite is a suitable precursor and a major source of world fluoride prozac HF production, HF is also. Apatite sources typically contain a few percent of fluoroapatite, acid digestion of which releases 80 mg of prozac a gaseous stream consisting fluoride prozac of sulfur dioxide (from the H2SO4 water, and HF, as well as particulates. After separation from the solids, the gases are treated with sulfuric acid and oleum to afford anhydrous. Owing to the corrosive nature of HF, its production is accompanied by the dissolution of silicate minerals, and, in this way, significant amounts of fluorosilicic acid are generated. 4 Hydrofluoric acid has a variety of uses in industry and research. It is used as a starting material or intermediate in industrial chemistry, mining, refining, glass finishing, silicon chip manufacturing, and in cleaning. 7 Oil refining edit In a standard oil refinery process known as alkylation, isobutane is alkylated with low-molecular-weight alkenes (primarily a mixture of propylene and butylene ) in the presence of the strong acid catalyst derived from hydrofluoric acid. The catalyst protonates the alkenes (propylene, butylene) to produce reactive carbocations, which alkylate isobutane. The reaction is carried out at mild temperatures (0 and 30 C) in a two-phase reaction. Production of organofluorine compounds edit The principal use of hydrofluoric acid is in organofluorine chemistry. Many organofluorine compounds are prepared using HF as the fluorine source, including Teflon, fluoropolymers, fluorocarbons, and refrigerants such as freon. 4 Production of fluorides edit Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid. Foremost are Na3AlF6, cryolite, and AlF3, aluminium trifluoride. A molten mixture of these solids serves as a high-temperature solvent for the production of metallic aluminium. Given concerns about fluorides in the environment, alternative technologies are being sought. Other inorganic fluorides prepared from hydrofluoric acid include sodium fluoride and uranium hexafluoride. 4 Etchant and cleaning agent edit Wet etching tanks In metalworking, hydrofluoric acid is used as a pickling agent to remove oxides and other impurities from stainless and carbon steels because of its limited ability to dissolve steel. Citation needed It is used in the semiconductor industry as a major component of Wright Etch and buffered oxide etch, which are used to clean silicon wafers.
Does prozac help with depression
Prozac does have some anti-anxiety properties. Initially, when starting, anxiety may still be present and then improve the longer you are.

If you dont notice any change in your mood after a few weeks, talk with your doctor. If the first antidepressant you take doesnt work, its likely that another one will. About 60 of people who take antidepressants feel better with the first medicine they take, but others need to try more than one before noticing a change. A study funded by the National Institute. Mental Health in 2008 found that about 50 of patients who did not feel better after using one medication noticed an improvement when they took a new one or added a second does prozac help with depression medication to the first treatment. You and your doctor can work together to find the medication thats right for you. I had to try a couple of different kinds of medications to find the right one for me, Brennan tells WebMD. One medication worked for a little while, and then I started to feel depressed again. So my doctor switched me to another medication, and that one is working great.
