Boric acid (H₃BO₃) is a naturally occurring compound of boron, oxygen, and hydrogen. It is a white, odourless powder with mild acidity and is widely used across industrial, agricultural, and pharmaceutical sectors. Boric acid is valued for its flame-retardant properties, low toxicity, and effectiveness as a mild antiseptic and wood preservative.
