Sodium salts are compounds formed when sodium ions combine with anions, which are negatively charged ions. Common examples include sodium chloride (table salt) and sodium bicarbonate (baking soda). These salts are widely used in food preservation, cooking, and various industrial applications due to their ability to enhance flavor and act as preservatives. In addition to their culinary uses, sodium salts play important roles in biological processes. For instance, they help maintain fluid balance in the body and are essential for nerve function. Sodium ions are crucial for muscle contraction and are found in many cellular processes, making them vital for overall health.
