Copper hydroxide 2 is formed by interactions ..

There are several options, let’s consider the simplest one. Take the copper sulfate salt and sodium hydroxide base. As a result of the exchange reaction that these two compounds undergo, we get another salt and another base, namely the sodium sulfate salt and the bivalent copper hydroxide we need. Copper hydroxide, practically insoluble in water and has a pronounced blue color. Graphically, this chemical reaction can be written with the following equation:
CuSO4 + 2 NaOH = Cu (OH) 2 + Na2SO4.
