CADMIUM SULFATE 

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Cadmium sulfate is the sulfate salt of cadmium. Cadmium ions (Cd²⁺) and sulfate ions (SO₄²⁻) are present in a 1:1 ratio. The compound typically exists in anhydrous form or as hydrates (monohydrate, octahydrate). It is hygroscopic and readily absorbs moisture from the air. It is a highly toxic heavy metal salt.
