👩‍🔬 This is the decomposition of hydrogen peroxide catalyzed by potassium iodide.⁠ The hydrogen peroxide is mixed with washing-up liquid and food coloring. ⁠ ⁠ Then the catalyst (potassium iodide), is added. The products of the decomposition of hydrogen peroxide are water and oxygen; the oxygen gas gets trapped by the washing up liquid and fluffy foam is suddenly produced.⁠ ⁠ _____⁠ ⁠ 📹️ courtesy of: @emilia.science⁠ ⁠ ⁠ #chemistry #scienceismagic #science #scientist #stem #scienceisfun
