Why is copper(II) hydroxide not a salt?

Reason 1 :

Because a " Salt " is defined as Product ( other than Water ) from Neutralization of Acid and Base ( Alkali ) .

Reason 2 :

Because Copper (II) hydroxide will perform as a Base when reacts with acids .

Reason 3 : [ actually this is the first reason ]

Because it was originally classified as a " Base "

( Metal oxides and Metal hydroxides are originally classified as a " Base " or Alkali ) .

In order for something to be a salt it has to be the product of a reaction between an acid and base.

You can see it is a base by looking at the formula Cu(OH)2 the OH indicates it is a base. If you want to look for an acid you look for something like H2SO4 where there is a hydrogen in front of the formula.

A salt is produced when a acid reacts with a base. For example, CuSO4. Copper (II) hydroxide, as you can see from the (OH), is a base.

it is not a salt because the oxygen and hydrogen are bonded covalently. salts contain only ionic bonds.
