Question

98 БАЛЛОВ. Подскажите, по какой причине эти электролиты могут не реагировать с раствором соляной кислоты? Например, сульфат меди(II), нитрат натрия, оксид фосфора(V)?

Answer 1

Насколько я помню они не проходят по правилу Бертолле. То есть при реакции должны появится осадок/малодиссоциинируемое вещество или вода/выделение газа.

Answer 2

Possible Reasons for Lack of Reaction with Hydrochloric Acid

There could be several reasons why certain electrolytes, such as copper(II) sulfate, sodium nitrate, and phosphorus(V) oxide, may not react with hydrochloric acid. Here are a few possible explanations:

1. Solubility: Some electrolytes may have limited solubility in hydrochloric acid, which can hinder their reaction. Solubility refers to the ability of a substance to dissolve in a particular solvent. If an electrolyte has low solubility in hydrochloric acid, it may not come into contact with enough acid molecules to initiate a reaction.

2. Reaction Kinetics: The rate at which a chemical reaction occurs can also influence whether a reaction takes place or not. Even if an electrolyte is soluble in hydrochloric acid, the reaction may be slow or may require specific conditions (such as elevated temperature or the presence of a catalyst) to proceed at a noticeable rate. Without these favorable conditions, the reaction may not occur or may proceed too slowly to be easily observed.

3. Chemical Stability: Some electrolytes may be chemically stable in hydrochloric acid, meaning they do not readily undergo a reaction with the acid. This could be due to the nature of the chemical bonds present in the electrolyte, which may be resistant to breaking in the presence of hydrochloric acid.

It's important to note that the lack of reaction with hydrochloric acid for these specific electrolytes is based on the information provided in the question. Further analysis and experimentation may be required to confirm these explanations.
