Base salts are chemical compounds formed when a base reacts with an acid, resulting in a salt and water. They typically consist of a metal cation and a non-metal anion. Base salts can be found in various forms, such as sodium chloride or potassium sulfate, and are commonly used in industries like agriculture and food processing. These salts play a crucial role in maintaining pH balance in soil and water, which is essential for plant growth and aquatic life. Additionally, base salts are often utilized in the production of fertilizers, helping to enhance crop yields and improve soil health.
