Alkalis

Alkalis are water-soluble bases that release hydroxide ions (OH⁻) when dissolved in water, resulting in an alkaline solution. They have a bitter taste, slippery feel, and turn red litmus paper blue. Common examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and ammonium hydroxide (NH₄OH). Alkalis are widely used in industries like cleaning, water treatment, soap production, and chemical manufacturing due to their ability to neutralize acids and break down organic materials.
