Alkalis are a group of chemical compounds that can neutralize acids. They are typically soluble in water and produce hydroxide ions (OH⁻) when dissolved. Common examples of alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH). These substances are often found in household products like cleaning agents and drain cleaners. Alkalis are part of a larger category known as bases, which are substances that can accept protons or donate electron pairs. They play a crucial role in various chemical reactions and are important in industries such as manufacturing and agriculture. Understanding alkalis is essential for studying chemistry and its applications.
