Acids, bases, and salts are fundamental chemical compounds. Acids produce hydrogen ions (H+) in water, have a sour taste, and react with metals. Bases produce hydroxide ions (OH-) in water, feel slippery, and have a bitter taste. When an acid and a base react, they neutralize each other, forming salts and water. Salts are ionic compounds with various uses. Understanding these substances is crucial in chemistry and everyday life.
