hydrofluoric acid vs hydrochloric acid

More useless info: - In the state of Tenn. it is required to register buyers of Muratic/Hydrochloric Acid of $50 or more and seller has to keep info on file for 3 years (3 forms of ID. Therefore, when diluting hydrochloric acid, water should be added to the acid carefully, but not the other way (adding acid to water). The dissociation of this acid gives hydronium ions (combination of protons and water molecules form hydronium ions) and fluoride ions. The hydrofluoric acid molecule has a fluoride ion whereas the hydrochloric acid molecule has a chloride ion. You can sign in to give your opinion on the answer. At high concentrations, HF molecules undergo homoassociation to form polyatomic ions (such as bifluoride, HF 2) and protons, thus greatly increasing the acidity. Hydrochloric acid is a strong acid - meaning that it is completely dissociated in solution, and hydrofluoric acid is a weak acid - meaning that it is not completely dissociated in solution. Hydrochloric acid is an aqueous hydrogen chloride. Hydrofluoric acid is hydrogen fluoride in water.

The persistent burns and usual deep-seated ulcerations occur due to interaction between aqueous hydrofluoric acid and skin, and Iintake of concentrated vapors result into lung damage. Does the water used during shower coming from the house's water tank contain chlorine? Hydrofluoric acid is produced by treatment of the mineral fluorite (CaF 2) 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: . 1. Thus, this acid has a high Ka value. Hydrofluoric acid is a weak acid. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. What do you think of the answers? I know that ABF is safer to handle than HF or HCl but I'm not sure how safe. One of the reasons for all the wing-nut objections to water fluoridation is the toxicity of the fluoride ion. Quite simple - which is more aggressive? Commercially concentrated acid is around 40wt. If so, I bet that is the last time you did it! In general, hydrofluoric acid is less corrosive than hydrochloric acid because it passivates most metals. Therefore, these acid molecules can ionize in aqueous mediums releasing protons (H+). It is used in oil industry due to the fact that it can dissolve siliceous materials. Acids are molecules which are capable of donating protons or H+ ions to an aqueous solution. HF on the other hand is a different beastie. Hydrofluoric Acid . HCl is stronger than HF, BUT Hydrofluoric acid is MUCH more dangerous to humans. Also I have heard that HF skin burns tend to essentially not heal. Hydrochloric acid is also used in the food industry. Unlike HF, HCl is a strong acid that can completely ionize in the aqueous medium, forming hydronium ions and chloride ions. Few compounds are more corrosive than hydrofluoric acid – and Monel fasteners is one of the few can survive hydrofluoric acid (HF). The fluoride ion is so reactive it pulls calcium out of the bones to form insoluble CaF2. Available here, 1.’Hydrogen fluoride’By User:Dorgan – Self-photographed, (CC BY-SA 3.0) via Commons Wikimedia   However, if these films are destroyed by dilution or else, severe corrosion in the form of hydrogen blistering of carbon steel and stress cracking of hardened bolts will occur. The hydrochloric acid reacts rapidly with water, results in boiling or splattering. This means that in solution, virtually all the hydrochloric acid molecules will have donated a hydrogen ion to a water molecule, while in a phosphoric acid solution, only a fraction of the phosphoric … Overview and Key Difference What is the  molar concentration of sodium nitrate .?
