Identificación de Nitritos Y Nitratos
PRUEBAS DE IDENTIFICACION DE NITRITOS Y NITRATOS EN SOLUCION ACUOSA

RESUMEN.

Dentro del desarrollo de este tema encontramos primero la descripción de las propiedades del ion nitrito, el cual esta formado por un átomo de N y dos de O con una carga de -1, por consecuencia tiene una geometría angular; dentro de la propiedades útiles para su identificación tenemos que es un ion soluble en agua, es incoloro y puede actuar como oxidante o reductor. Forma complejos ya sea por parte de el átomo de O ó por del átomo de N.

En cuanto a el ion nitrato esta formado por un átomo de N central y tres átomos de O con una carga de –1, estabilizado por una resonancia de tres estructuras equivalentes; en cuanto a sus propiedades utililes para el análisis cualitativo, este ion es soluble en agua y actúa como oxidante, y puede formar complejos ya sea unidentados, bidentados o tridentinos, y no forma compuestos que precipiten.

SUMMARY

Within the development of this issue we first find the description of the properties of nitrite, which is formed by a nitrogen atom and two O with a charge of -1, consequently has a bent geometry, within the useful properties identification we need is a water-soluble ion is colorless and can act as an oxidizer or reducer. Complex way by either the O atom by atom or N.
As for the nitrate ion is formed by a central N atom and three O atoms with a charge of -1, stabilized by a resonance of three equivalent structures, in terms of their properties utililes for qualitative analysis, this ion is soluble in water and acts as an oxidant, and may form complexes either unidentate, bidentate or Tridentine, and do not form compounds that precipitate.

PROPOSITO: proponer reacciones de identificación en solución acuosa para la determinación cualitativa de ion nitrito (NO₂⁻) y nitrato (NO₃⁻).

PURPOSE: to propose identification reactions in aqueous solution for the qualitative determination of nitrite (NO ₂ ⁻) and nitrate (NO ₃ ⁻).

    Begin building the chemical equation by dragging a sodium ion to the first product box and a nitrate ion to the second product box. Place your cursor over each ion to display its charge. Since these ions have equal but opposite charges (+1 and -1), you do not need to drag any additional ions to this area. NaNO3 is a valid chemical formula.…

    The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water, the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions, write balanced equations, and to write net ionic equations for precipitation reactions. A detailed view of the results can be found in the table below.…

    This experiment seeks to explore different chemical reactions conducted in the lab. A cation is defined as positively charged ions, which are K+ and Pb2+ in this experiment, and an anion is termed as negatively charged ions, which are CrO4 2- and NO3 2-. The major objective of this lab experiment was to examine the reaction between cations and anions, as well as observing, and documenting the chemical reactions. We will be demonstrating the reaction between a solution of Lead Nitrate with a chemical formula of PbNO3 2, and a Potassium Chromate solution with a chemical formula of K2CrO4. The end result from mixing the two solutions should have a combined set of either the Pb2+ or K+ cation and likewise with the NO3 2- or CrO4 2- anion in its chemical formula. This experiment will demonstrate the chemical reaction between the cations and anions with an expected end result of a solid substance, which validates that a chemical reaction occurred.…

    Nitric acid, or known as NHO3aq is an acid formed from reaction of ammonia and oxygen. Nitric acid is a colourless acid when it’s pure, or can be found yellow or red. This acid can be very corrosive to eyes and skin and can cause severe burns to human skin and tissues. It is miscible to water, and has a very pungent smell. Nitric acid is very reactive and can is able to melt many metals, and non metals. As a solution, nitric acid is known as a good conductor of electricity. When combining ammonia and oxygen, water and nitrogen, it is known as nitric acid.…

    NO3- or otherwise known as Nitrate, not to be confused with Nitrite, is located in period 2 group 15. Nitrate is an element that can not be observed by any of the senses other than sight and touch because it is known to be odorless and tasteless. Nitrate starts within the earths soil but filters into water and plants when it is mixed with rain water that is either cycled back into larger bodies of water or into the plants that take the water from the soil. The plants use the nitrate to satisfy nutrient requirements. the nitrate molecules will often filter into the leaves and stems of the plants. Nitrate is normal quite harmless in water when there isn't such a high quantity of it within the water one is consuming. If to much nitrate is consumed it can often cause methemoglobinemia This can cause less oxygen to reach certain tissues such as the brian which can often result in death. Methemoglobinemia is more likely to occur within infants or younger children due to their lack of years to develop to the effects of higher concentrations of nitrate. But it is not uncommon for it to occur in adults with an abnormally low production of the methemoglobin enzyme.…
