Zeolite is _______? Answer: Hydrated sodium aluminum silicate

Zeolites are hydrated sodium aluminum silicates that act as ion-exchange materials. They are mainly used in water softening because they can replace calcium (Ca²⁺) and magnesium (Mg²⁺) ions (which cause hardness) with sodium (Na⁺) ions. This property makes zeolites very useful in detergents and water purification systems.
