What is the composition of the polyatomic ion of hypochlorite?

The correct answer indicates that the composition of the hypochlorite ion consists of chlorine and oxygen. Hypochlorite is a polyatomic ion with the chemical formula ClO⁻, which reveals that it is made up of one chlorine atom (Cl) and one oxygen atom (O) with an overall negative charge. This composition is significant as it defines the ion's reactivity and properties in various chemical contexts, such as in disinfection and bleaching.

In summary, understanding that hypochlorite is composed solely of chlorine and oxygen is fundamental in recognizing its role in chemical reactions and its applications in fields like environmental science, chemistry, and funeral service.
