O chamado jardim químico é um experimento clássico de química que mostra, de forma visual, como ocorrem reações de precipitação, difusão e formação de estruturas auto-organizadas. Nesse caso, a solução contém silicato de sódio (Na₂SiO₃), um composto solúvel que libera íons silicato na água. Quando soluções de sulfato de cobre (CuSO₄), cloreto férrico (FeCl₃) e cloreto de cobalto (CoCl₂) entram em contato com essa solução, os íons metálicos Cu²⁺, Fe³⁺ e Co²⁺ reagem imediatamente com os íons silic
