An alkaline solution is a type of solution that has a pH level greater than 7. This means it is less acidic and can neutralize acids. Alkaline solutions are often formed when a base, such as sodium hydroxide or potassium hydroxide, dissolves in water. They are commonly found in household products like cleaning agents and baking soda. These solutions can have various applications, including in agriculture to improve soil quality and in medicine to help balance body pH levels. Understanding alkaline solutions is important in fields like chemistry, biology, and environmental science, where pH plays a crucial role in reactions and processes.
