Question

Терміново!!! запишіть реакції йонного обміну між попарно взятими речовинами в повному молекулярному , йоному та скороченому йоному вигляді Cu(NO2)2 і KOH

Answer 1

Реакція між Cu(NO2)2 і KOH у повному, йонному та скороченому йонному вигляді виглядає наступним чином:

Повний молекулярний вигляд:
Cu(NO2)2 + 2KOH → Cu(OH)2 + 2KNO2

Йонний вигляд:
Cu^2+ + 2NO2^- + 2K^+ + 2OH^- → Cu(OH)2 + 2K^+ + 2NO2^-

Скорочений йонний вигляд:
Cu^2+ + 2OH^- → Cu(OH)2

Answer 2

Reactions of Ionic Exchange Between Copper Nitrite (Cu(NO2)2) and Potassium Hydroxide (KOH)

When copper nitrite (Cu(NO2)2) reacts with potassium hydroxide (KOH), an ionic exchange reaction occurs. Let's examine the reactions in the full molecular, ion, and abbreviated ion forms.

1. Full Molecular Equation: The full molecular equation represents the reaction using the complete chemical formulas of the compounds involved. In this case, the reaction can be represented as follows:

Cu(NO2)2 + 2 KOH → Cu(OH)2 + 2 KNO2

2. Ionic Equation: The ionic equation represents the reaction by separating the compounds into their respective ions. In this case, the reaction can be represented as follows:

Cu^2+ + 2 NO2^- + 2 K^+ + 2 OH^- → Cu(OH)2 + 2 K^+ + 2 NO2^-

3. Abbreviated Ionic Equation: The abbreviated ionic equation eliminates the spectator ions (ions that appear on both sides of the equation and do not participate in the reaction). In this case, the spectator ions are K^+ and NO2^-. The abbreviated ionic equation can be represented as follows:

Cu^2+ + 2 OH^- → Cu(OH)2

To summarize: - The reaction between copper nitrite (Cu(NO2)2) and potassium hydroxide (KOH) results in the formation of copper hydroxide (Cu(OH)2). - The full molecular equation is Cu(NO2)2 + 2 KOH → Cu(OH)2 + 2 KNO2. - The ionic equation is Cu^2+ + 2 NO2^- + 2 K^+ + 2 OH^- → Cu(OH)2 + 2 K^+ + 2 NO2^-. - The abbreviated ionic equation is Cu^2+ + 2 OH^- → Cu(OH)2.
