Elephant's Toothpaste 30% hydrogen peroxide is added to a glass cylinder containing a concentrated aqueous mixture of potassium iodide and dishwashing soap. All you need is hydrogen peroxide, dish soap, potassium iodide and a little food coloring to create this colorful eruption of foam. The biological catalyst, catalase, speeds up the decomposition of hydrogen peroxide fairly quickly but there are chemical catalysts that cause the reaction to occur much more rapidly. Procedure: Either way, it's a good idea to do the experiment outside, since it involves so much spillover. It was adjusted to a specified pH, between 7 and 9, in each experiment by the addition of 1 M HCl or 1 M NaOH. Fortunately, the foam is just water, soap, and oxygen, and will release oxygen on its own until you're left with soapy, colored water. The soapy water traps the oxygen, creating bubbles, and turns into foam. Cap and shake until all the potassium iodide is dissolved (This should now be a saturated solution of KI made with 15 grams of KI and water.) Fill the vial containing potassium iodide with water. 13 years ago . Developer is not labeled by concentration 20v is 6% 30v is 9.9% and 40 v is 12%.
