How to write the formula for hydrofluoric acid (HF)?
- A strongest acid will give a weakest conjugate base. ...
- In this example of HF,H2O, H-COOH and HCN ,the pKa Values are 3.14, 14.0, 3.75, 9.21 respectively.
- So HF, is the strongest acid among the given acids. ...
- HF--------->H+ + F-.
- The H+ ion removed part of the acid is called the conjugate base.
How to write the formula for hydrobromic acid (HBr)?
The formula for hydrobromic acid is HBr, it is a strong acid formed by the dissolution of hydrogen bromide (HBr) in water. It is therefore a watery solution containing bromide ions and hydronium ions, so it can be used to prepare bromine salts: bromide.

What is the color of hydriodic acid?
Hydriodic acid appears as a colorless to yellow liquid with a pungent odor. Consists of a solution of hydrogen iodide in water. Fumes irritate the eyes and mucous membranes. Corrosive to metals and to tissue.
Why is hydroidic acid stored?
Hydroidic acid must be stored to avoid contact with strong acids (such as hydrochloric, sulfuric and nitric), chemically active metals (such as potassium, sodium, magnesium and zinc ), and strong oxidizers (such as chlorine, bromine, and fluorine) since violent reactions occur.
When working with strong solutions of acids or bases or other caustic or corrosive materials, always wear answer
SRP: When working with strong solutions of acids or bases or other caustic or corrosive materials, always wear a full face mask. When working with caustic or corrosive gases or vapors, a full face mask will not protect the eyes or prevent inhaling the material. A full face respirator is required.
Is iodine 125 a radioactive isotope?
Iodine I-125 is a radioactive isotope of iodine, a non metallic element of the halogen group. With a half-life of 60 days, iodine 125 occurs naturally and can be produced artificially. This agent has both therapeutic and diagnostic uses, particularly in thyroid disease.
Is hydrogen iodide toxic?
Hydrogen iodide, anhydrous appears as a colorless to yellow/brown gas with an acrid odor. Nonflammable. Toxic by inhalation. Strongly irritates skin, eyes and mucous membranes. Long-term inhalation of low concentrations or short-term inhalation of high concentrations may result in adverse health effects.
What is hydroiodic acid?
Like other hydrogen halides, hydroiodic acid add s to alkenes to give alkyl iodides. It can also be used as a reducing agent, for example in the reduction of aromatic nitro compounds to anilines.
Is hydroiodic acid a DEA substance?
Hydroiodic acid is listed as a U.S. Federal DEA List I Chemical, owing to its use as a reducing agent related to the production of methamphetamine from ephedrine or pseudoephedrine (recovered from nasal decongestant pills).
What is the chemical formula for hydroiodic acid?
The chemical formula for hydroiodic acid is HI. Hydroiodic acid is a strong acid made by dissolving hydrogen iodide in water.
What is hydroiodic acid used for?
Uses of Hydroiodic Acid – HI. Used in the manufacture of iodides and as a reducing agent and in disinfectants and pharmaceuticals. Used as one of the primary sources of iodine in organic and inorganic synthesis.
Is halide acid aqueous or gas?
However both differ in the physical state one is gas and the other is an aqueous solution. It is one of the strongest of all common halide acids due to high stability of its corresponding conjugate base.
Is hydroiodic acid harmful to the skin?
Health Hazard – HI. Hydroiodic acid is a corrosive liquid that in contact with the skin can produce burns. Acid contact with the eyes may cause severe irritation. A strong irritant to the eyes, skin and mucous membranes is the gas hydrogen iodide. Test your Knowledge on Hydroiodic acid!
What is Hydroiodic Acid?
The aqueous solution of hydrogen iodine is named as the hydroiodic acid and it is quite common and acidic too among hydrohalides. The chemical formula for the substance is HI with a molar mass of 127.91g/mol. The substance is available in the gaseous form and hydroiodic acid is the aqueous solution of HI and interchangeable with hydrogen chloride.
Hydroiodic Acid Chemical Formula
This is polarized in nature and connected to each other due to electronegativity nature of the iodine compound. Because of the large size of iodine ion, the negative charge gets dispersed and results in a weaker HI bond. It allows H+ to dissociate quickly and quite stronger when compared to others like HCl, HBr or HF etc.
Hydroiodic Acid Molecular
In the end, you can see that HI will get distilled to give the hydroiodic acid in the needed concentration. It is colorless in nature with an acrid odor and quickly soluble in the water to make the hydrochloride acid. The concentration of hydroiodic acid in water is usually 48 percent to 57 percent.
