Cu(OH)₂(s) + 2NaNO₃(s) → Cu(NO₃)₂(s) + 2NaOH(s)
Here's a breakdown of what happens:
* Decomposition of copper(II) hydroxide: When heated, copper(II) hydroxide decomposes to form copper(II) oxide (CuO) and water (H₂O):
Cu(OH)₂(s) → CuO(s) + H₂O(g)
* Reaction with sodium nitrate: The sodium nitrate will react with the copper(II) oxide to form copper(II) nitrate (Cu(NO₃)₂) and sodium hydroxide (NaOH):
CuO(s) + 2NaNO₃(s) → Cu(NO₃)₂(s) + 2NaOH(s)
Overall Reaction:
The overall reaction can be represented as the combination of the above steps:
Cu(OH)₂(s) + 2NaNO₃(s) → Cu(NO₃)₂(s) + 2NaOH(s)
Important Notes:
* This reaction is an example of a double displacement reaction.
* The reaction is not very vigorous and will likely proceed slowly.
* The products, copper(II) nitrate and sodium hydroxide, are both soluble in water.
* The water produced in the decomposition of copper(II) hydroxide will evaporate, leaving behind the solid products.
Safety Precautions:
* Copper(II) hydroxide is a mild irritant.
* Sodium nitrate is a strong oxidizer.
* Always wear appropriate safety gear, such as gloves and eye protection, when handling chemicals.
