Question

Cu(OH)2+NaOH как происходит реакция? Почему реакция не происходит? Помогите пожалуйста.

Answer 1

Cu(oh)2 + 2naoh =na2[cu(oh)4]

cu(oh)2 в избытке щелочи растворяется!

Answer 2

Reaction between Cu(OH)2 and NaOH

The reaction between Cu(OH)2 (copper hydroxide) and NaOH (sodium hydroxide) can be represented by the following equation:

Cu(OH)2 + 2NaOH → Na2Cu(OH)4

In this reaction, copper hydroxide reacts with sodium hydroxide to form sodium tetrahydroxocuprate(II). The copper hydroxide compound is a base, while sodium hydroxide is a strong base. When they react, the hydroxide ions (OH-) from both compounds combine to form the tetrahydroxocuprate(II) ion.

Why the reaction may not occur

There are several reasons why a reaction between Cu(OH)2 and NaOH may not occur:

1. Insufficient reactants: If there is an insufficient amount of either Cu(OH)2 or NaOH, the reaction may not proceed to completion. The reaction requires a stoichiometric ratio of 1:2 between Cu(OH)2 and NaOH.

2. Presence of other compounds: If there are impurities or other compounds present in the reaction mixture, they may interfere with the reaction and prevent it from occurring.

3. Temperature and concentration: The reaction between Cu(OH)2 and NaOH is typically favored at higher temperatures and higher concentrations. If the temperature or concentration is too low, the reaction may not proceed effectively.

4. pH: The pH of the reaction mixture can also affect the reaction. If the pH is too acidic or too basic, it may hinder the reaction between Cu(OH)2 and NaOH.

It's important to note that the specific conditions and factors that affect the reaction between Cu(OH)2 and NaOH may vary depending on the experimental setup and other factors. It's always recommended to consult reliable sources and conduct experiments under controlled conditions to determine the specific outcomes of chemical reactions.
