Sulphates and sulphonates

Sulfates and sulfonates are two important groups of chemical compounds that contain a sulfate (SO₄²⁻) or sulfonate (SO₃⁻) functional group, respectively. A sulfate is an inorganic anion composed of one sulfur and four oxygen atoms, carrying two negative charges. A sulfonate is an organic compound whose structure includes a group of sulfur and three oxygen atoms attached to an organic fragment (R-SO₃⁻).

Properties and Applications of Sulfates and Sulfonates

Sulfates are widely used in agriculture as an effective source of sulfur for plants. Sulfur is an essential element for the synthesis of proteins and enzymes, so these compounds help maintain a proper nutritional balance and plant development. Due to their good solubility in water, sulfates are quickly absorbed by roots and do not cause micronutrient deficiencies, such as chlorosis.

Sulfonates are most commonly used as anionic surfactants. They reduce the surface tension between a liquid and a solid surface, thereby improving the removal of dirt in detergents and cleaners. Their negative charge allows for the effective dispersion of poorly soluble compounds, especially in aqueous media.

Due to their chemical stability, sulfonates are also used in the production of dyes, pharmaceuticals, and paper. Both types of these compounds are important in both industrial and environmental technologies – they help control metal ions, improve solubility, and ensure effective performance in various chemical systems.
