Question

Докажите экспериментально. что в хлориде присутствует ионы хлористого водорода и хлора. Напишите необходимое уравнение реакции​

Answer 1

Для определения хлористого водорода используем Магний
Mg+ 2HCl=MgCl2+H2 выделяется газ Водород , индикатором этого может быть спичка
Для обнаружения ионов хлора возьмём реакцию с Натрий гидроксидом
NaOH + HCl= NaCl+H2O , если выпарить раствор получим NaCl что и является доказательством присутствия ионов Хлора

Answer 2

Experiment to Demonstrate the Presence of Hydrogen Chloride and Chlorine Ions in Hydrogen Chloride

To experimentally demonstrate the presence of hydrogen chloride (HCl) and chlorine (Cl) ions in hydrogen chloride, we can perform a simple reaction with a substance that reacts specifically with either the hydrogen ion or the chloride ion.

Reaction with Silver Nitrate (AgNO3)

When hydrogen chloride reacts with silver nitrate (AgNO3), a white precipitate of silver chloride (AgCl) is formed. This reaction demonstrates the presence of chloride ions in hydrogen chloride.

The balanced chemical equation for this reaction is:

HCl + AgNO3 → AgCl + HNO3

This reaction shows that chloride ions are present in hydrogen chloride, as they react with silver nitrate to form silver chloride.

Reaction with Sodium Hydroxide (NaOH)

When hydrogen chloride reacts with sodium hydroxide (NaOH), it forms water and sodium chloride (NaCl). This reaction demonstrates the presence of hydrogen ions in hydrogen chloride.

The balanced chemical equation for this reaction is:

HCl + NaOH → H2O + NaCl

This reaction shows that hydrogen ions are present in hydrogen chloride, as they react with sodium hydroxide to form water and sodium chloride.

Conclusion

By performing these two reactions, we can experimentally demonstrate the presence of both hydrogen ions and chloride ions in hydrogen chloride.
