What is the chemical formula for acetate?

The chemical formula for acetate is represented as C2H3O2(-). This formula indicates that acetate is a negatively charged ion (an anion) derived from acetic acid. In this structure, there are two carbon atoms, three hydrogen atoms, and two oxygen atoms, which collectively contribute to the overall negative charge.

This ion is significant in organic chemistry and biochemistry, as acetate can participate in various metabolic reactions and is involved in energy production in living organisms. Understanding the structure of acetate can help in recognizing how it interacts within different chemical processes and its role in various biological systems.

The other options provided are formulas for different ions. For example, the formula for phosphate (PO3(3-)), arsenate (AsO4(3-)), and borate (BO3(3-)) are distinct from acetate and pertain to different groups of compounds with differing properties and applications in chemistry. Recognizing these differences helps clarify why the acetate formula is unique and specifically defined as C2H3O2(-).
