The Twitter video probably shows the reaction with 30% hydrogen peroxide, or even stronger, Hostetler said. The demonstrator also uses potassium iodide that's in powder form instead of mixed into ...

K959: Prep Notes Introduction The reaction of hydrogen peroxide with potassium iodide is demonstrated in a tall cylinder. Saturated potassium iodide is added to a mixture of soap, glycerin, water, and ...

Footage shows a teacher demonstrating the 'Elephant toothpaste' experiment to his students. The instructor used a hydrogen peroxide solution and poured the substance into a small beaker containing ...

In 2019, the most-viewed video on TikTok—a short-form mobile video platform—was a chemistry experiment: a massive demonstration of the hydrogen peroxide–potassium iodide reaction known as ...

When you combine hydrogen peroxide with potassium iodide, the result is a prodigious volume of oxygen gas. Perform this reaction in a standard beaker, and this gas — which is colorless — will ...

Procedure Carefully pour ½ cup hydrogen peroxide into the plastic bottle and add a big squirt of dish soap. Swirl gently to mix. Add 2 to 3 drops of food coloring to the solution.

When the potassium iodide is added to the hydrogen peroxide solution, it acts as a catalyst, rapidly breaking down the hydrogen peroxide into oxygen and water.

"And there will be some loud noises." The experiment involves combining potassium iodide, hydrogen peroxide and soap. The result is an eruption of foam shooting skyward out of a beaker.
