AgI
Definition
AgI is the chemical formula for silver iodide, which is an ionic compound formed from silver cations (Ag⁺) and iodide anions (I⁻). It is sparingly soluble in water, meaning it does not readily dissolve.
Analogy
Think of AgI as tiny solid crystals made up of silver and iodine atoms. When these crystals come together in water, they form clumps like puzzle pieces fitting together.
