Johannes Nicolaus Brønsted

Johannes Nicolaus Brønsted was a Danish chemist known for his significant contributions to acidity and basicity in chemistry. He formulated the Brønsted-Lowry theory, which defines acids as substances that donate protons (hydrogen ions) and bases as those that accept protons. This theory expanded the understanding of chemical reactions beyond the traditional definitions and is foundational in explaining how substances interact in solutions. Brønsted's work helped to advance physical chemistry and has practical applications in fields like biochemistry and industrial processes. His insights remain essential for studying chemical behavior and reactions today.
