Commonly applied in agriculture as a micronutrient fertilizer to correct zinc deficiency in soils, improving crop yield and quality, especially in zinc-sensitive plants like corn, rice, and citrus. Employed in the synthesis of other zinc compounds and as a coagulant in the production of rayon. Utilized in medical treatments as an astringent and in eye drops for certain ocular conditions. Also serves in electrolyte solutions for zinc electroplating processes, contributing to corrosion resistance in metal coatings.
