Common silver objects used in these reactions include silver bullions and silver foils. The nitrate ion described above consists of one nitrogen atom which is surrounded by three oxygen atoms. Reaction stoichiometry could be computed for a balanced equation. The chemical equation for this reaction is given by. 2 AgNO 3 + Cu → 2 Ag + Cu(NO 3) 2. Despite its widespread usage (especially in extremely low amounts) for the prevention of gonorrhea, and to stop bleeding from the nose, silver nitrate is often highly toxic and corrosive. Silver nitrate is an oxidant and must, therefore, be kept away from organic compounds. The net charge associated by the nitrate ion is -1, which is quenched by the +1 charge held by the Ag+ ion via an ionic bond in AgNO3. Your email address will not be published. Molar Mass of AgNO3 Oxidation State of AgNO3. In its solid state, it has a density of 4.35 grams per cubic centimetre. when it is combined with nitrate a negative one ion, it takes two negative nitrates to equal the plus two of the copper. It can be noted that the structure of the nitrate ion is stabilized by resonance. Reaction Information. Compound states [like (s) (aq) or (g)] are not required. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. It is important to note that this reaction must be carried out under a fume hood because of the evolution of poisonous oxides of nitrogen during the chemical reaction. Silver nitrate has a wide range of applications in many fields such as biology, chemical synthesis, and medicine. The formal charge assigned to the nitrogen atom is -1, whereas each oxygen atom holds a charge of -⅔. Short-term exposure to this compound does not cause any immediate side effects apart from the development of a violet, brown or black stain on the part of the skin that was in contact with the silver nitrate. The reaction between silver nitrate and ethanol is explosive. However, exposure to this compound over long periods of time is often accompanied by damage to the eyes. Its density in the liquid state at a temperature of 210. Direct link to this balanced equation: Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. copper II is a plus two ion. Cu + 2AgNO3 ---> Cu (NO3)2 + 2Ag Source (s): MA (Oxon) The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. The silver present in this compound is displaced by copper, which forms copper nitrate. Due to the ability of this compound to form a precipitate of silver halides when treated with halide ions, it is used while making photographic films. the ratio between Cu and AgNO3 is 1 : 2. moles AgNO3 required = 2.4 x 2 = 4.8. we have 5.5 moles AgNO3 so AgNO3 is in excess and Cu is the limiting reactant Colloidal silver is produced when gelatine-containing, aqueous silver solutions absorb ionizing radiation. The branch of chemistry known as analytical chemistry uses this reaction to check for the presence of halide anions such as the iodide, bromide, or chloride ions. This compound is also known to be used for the treatment and the removal of unwanted warts in human beings. This compound is widely classified as an irritant to the skin and the eyes. Silver nitrate is widely used in many organic synthesis reactions in several ways. Silver nitrate is a chemical compound with the formula AgNO3. The resulting adduct can be decomposed (in order to release the free alkene) with ammonia. Favourite answer Grey solid crystals of silver metal are seen growing on the piece of copper metal, and the solution slowly turns blue. The molar mass of silver nitrate is 169.872 grams per mole. It consists of an ionic bond between the silver cation (Ag+) and the nitrate anion (NO3–). Enter either the number of moles or weight for one of the compounds to compute the rest. It can be observed that silver has an oxidation number of 1 in this compound. Mixtures of alkenes can be separated with the help of this compound since the silver cation binds with alkenes in a reversible fashion. In the presence of organic solutes, decrease is increased.
