What is the chemical formula for the sulfate ion

The sulfate ion is represented by the chemical formula SO₄²⁻. It consists of one sulfur atom (S) centrally bonded to four oxygen atoms (O) arranged in a tetrahedral shape. The sulfate ion carries a -2 charge due to the presence of four oxygen atoms, which collectively contribute to two additional negative charges. Sulfate is an essential component in various biological and environmental processes, including cellular respiration and the formation of acid rain. It's commonly found in fertilizers and is crucial for plant growth.
