The reaction between copper nitrate (Cu(NO₃)₂) and water (H₂O) is a simple dissolution reaction. Here's why:

* Copper nitrate is a soluble salt: This means it readily dissolves in water.

* No new chemical species are formed: The copper nitrate simply breaks apart into its ions (Cu²⁺ and NO₃⁻) when it dissolves in water.

So, the products of the reaction are:

* Copper(II) ions (Cu²⁺)

* Nitrate ions (NO₃⁻)

* Water (H₂O)

The reaction can be represented as:

Cu(NO₃)₂ (s) + H₂O (l) → Cu²⁺ (aq) + 2NO₃⁻ (aq)

Where:

* (s) represents solid

* (l) represents liquid

* (aq) represents aqueous (dissolved in water)
