Iodine can de used in several ways. First as a disinfectant before a medical procedure such as surgery of getting stiches. It can be used for a vitimin supplement in individuals with iodine deficeincy (very rare in the USA). It can also be used to destroy the thyroid in cases of thyroid cancer. Since the thyroid is the primary user and absorber of iodine in the body, radioactive iodine in injected into the body and the thyroid absorbs it destroying the cancer as well as the thyroid. In addition, iodine can be used in patients in thyroid storm. By giving iodine to patients in storm, it induces a blockege of T3 and T4 release which is known as the Wolff Chaikof effect.
Yes, halides can contain silicon. Silicon can form halides by combining with elements such as fluorine, chlorine, bromine, and iodine to create silicon halides. Examples of silicon halides include silicon tetrafluoride (SiF4) and silicon tetrachloride (SiCl4).
The ionic equation between halides and silver nitrate involves the cation from silver nitrate combining with the anion from the halide compound to form a precipitate. For example, with chloride ions, Ag^+ from silver nitrate reacts with Cl^- from the chloride compound to form solid silver chloride (AgCl) precipitate. The net ionic equation would show the formation of the silver halide precipitate.
Silver nitrate is kept in colored bottles to protect it from exposure to light. Light can catalyze the decomposition of silver nitrate, causing it to form colloidal silver which can reduce its effectiveness. Colored bottles help to block out light and preserve the stability of the silver nitrate solution.
This is a precipitation reaction. Halides of silver are insoluble in water (except silver fluoride) whereas all nitrates are soluble in water. Sodium salts are soluble. Thus, silver iodide is the precipitate. Formula: AgNO3(aq) + NaI(aq) -> AgI(s) + NaNO3(aq)
The products of the double-replacement reaction between potassium chloride (KCl) and silver acetate (AgC2H3O2) are potassium acetate (KC2H3O2) and silver chloride (AgCl). This reaction occurs because the potassium ion (K+) switches places with the silver ion (Ag+) to form the new compounds.
Siver Halides are neither a metal or an alloy. They are a salt.
Silver halides absorb light to form elemental silver. This is the basis for the photographic film. This is an unusual reaction and is certainly not common to all ionic compounds. Silver halides are also unusually insoluble, again not a common property of ionic compounds. In fact silver halides have quite a lot of covalent character! I am sure teacher has something in mind but its certainly not in mine.
Solubility of the silver halides decreases down the group.The solubilities of silver halides decreases down the periodic table:AgF :Ksp=205AgCl:Ksp=1.8×10−10AgBr:Ksp=5.2×10−13AgI :Ksp=8.3×10−17
Silver salts. Mainly silver halides.
Alcoholic silver nitrate reacts with alkyl halides to form silver halide and alkyl nitrate compounds. This reaction is commonly used in organic chemistry to identify the presence of alkyl halides in a sample.
They turn black
It removes undeveloped silver halides from photographic emulsions. This leaves the silver behind, giving you a prnt that won't eventually turn black (because silver halides will eventually turn black on their own) or a negative light will pass through.
There are three silver halides used: silver bromide, silver chloride and silver iodide. Silver chloride doesn't absorb very much light and silver iodide is hard to develop. So they use silver bromide, with a little bit of the other two to make the emulsion work in ways silver bromide can't do alone.
For photographic plates silver halides are used.
Rutherfordium halides have limited practical uses due to the element's high radioactivity and limited availability. They are primarily used for scientific research purposes related to studying the properties of superheavy elements.
When developing film what does the developer do to develop the film?
These are silver halides as AgCl and AgBr.
