Question

Большинство солей азотной кислоты растворимы в воде тем не менее предложите уравнение реакции HNO3 с солью в результате которой образуется осадок. напишите ионное уравнение этой реакции

Answer 1

Можно предложить как минимум два варианта:

1. Реакция образования осадка гидроксида металла из гидроксокомплекса:
K[Al(OH)₄] + HNO₃ = KNO₃ + Al(OH)₃ + H₂O
[Al(OH)₄]⁻ + H⁺ = Al(OH)₃ + H₂O

2. Реакция образования нерастворимого нитрата:
BiCl₃ + HNO₃ + H₂O = BiONO₃ + 3HCl
Bi³⁺ + H₂O + NO₃⁻ = BiONO₃ + 2H⁺

Answer 2

Solubility of Nitric Acid Salts

Most nitric acid salts are soluble in water. However, there are exceptions, and the solubility can vary depending on the specific salt.

Reaction of Nitric Acid with a Salt

When nitric acid reacts with certain salts, it can result in the formation of a precipitate. One example of such a reaction is the reaction of nitric acid with silver chloride, which forms a precipitate of silver chloride.

The balanced chemical equation for this reaction is:

HNO3 + AgCl → AgNO3 + HCl

Ionic Equation for the Reaction

The ionic equation for the reaction between nitric acid and silver chloride is as follows:

H⁺ + NO₃⁻ + Ag⁺ + Cl⁻ → Ag⁺ + NO₃⁻ + H⁺ + Cl⁻

In this reaction, the nitric acid dissociates into H⁺ and NO₃⁻ ions, and the silver chloride dissociates into Ag⁺ and Cl⁻ ions. The ions then recombine to form the products, including the precipitate of silver chloride.

This reaction demonstrates the formation of a precipitate when nitric acid reacts with a specific salt, resulting in the production of a different salt and a new acid.
