The name of Cu²⁺ is copper(II) cupric.
Explanation: In chemistry, copper can exist in multiple oxidation states, the most common being +1 and +2. The +2 oxidation state is denoted as copper(II), which is often associated with the name ‘cupric’. The term cuprous refers to the +1 oxidation state, so it is essential to use the proper nomenclature to differentiate between these two states. Therefore, Cu²⁺ is accurately described as copper(II), or cupric.
