What else can I help you with?
Can you make elephant toothpaste without yeast?
Yes, you can make elephant toothpaste without yeast. Elephant toothpaste is typically created using hydrogen peroxide and a catalyst such as potassium iodide or sodium iodide. The reaction between hydrogen peroxide and the catalyst produces oxygen gas, which creates the foamy substance known as elephant toothpaste. Yeast is not necessary for this reaction to occur.
Acid and base that makes potassium iodide?
To make potassium iodide, you would need to first react iodine with potassium hydroxide. This will create potassium iodate, which can then be reduced to potassium iodide using a reducing agent like sulfur dioxide or hydriodic acid.
What is the chemical equation for the preparation of Lugol's solution using potassium iodide and iodine?
The chemical equation for the preparation of Lugol's solution using potassium iodide and iodine is 2KI + I2 -> 2KI3.
How do you make silver iodide with the help of silver nitrate and potassium iodide with suitable condition?
Dissolve each of the silver nitrate and potassium iodide separately in water, then mix the two solutions slowly with stirring. Silver iodide will precipitate and can be separated by filtering it from the liquid.
How can I make elephant toothpaste bigger?
To make elephant toothpaste bigger, you can increase the amount of hydrogen peroxide and yeast used in the reaction. This will produce more foam and create a larger reaction. Additionally, using a larger container or adding more dish soap can also help increase the size of the foam produced.
Can you make elephant toothpaste without yeast?

The reaction between hydrogen peroxide and the catalyst produces oxygen gas, which creates the foamy substance known as elephant toothpaste. Yeast is not necessary for this reaction to occur.
What is the purpose of elephant tooth paste?
It is a chemical experiment using hydrogen peroxide and potassium iodide, mixed with detergent and water. If you add all these together, the hydrogen peroxide's decomposition is sped up by the catalyst, potassium iodide. Oxygen is given off and forms foam with the detergent. The foam pushes up in the cylinder or test tube and comes out the top looking like toothpaste, hence elephant's toothpaste.
Does elephant toothpaste work when you add dry yeast?
Yes, elephant toothpaste can work with dry yeast as a catalyst for the reaction. Dry yeast contains enzymes that break down hydrogen peroxide into water and oxygen, producing a rapid release of oxygen gas that creates the foamy eruption characteristic of elephant toothpaste. However, the reaction may not be as vigorous as when using liquid yeast or other catalysts like potassium iodide. It's important to ensure the yeast is activated properly for the best results.
What are some Elephant toothpaste fun facts?
Elephant toothpaste is a popular science experiment that demonstrates an exothermic reaction, typically using hydrogen peroxide, soap, and yeast or potassium iodide as catalysts. The reaction produces a large, foamy eruption resembling a giant tube of toothpaste, hence the name. This experiment highlights concepts such as catalysis and the rapid decomposition of hydrogen peroxide. It's safe and visually striking, making it a favorite for educational demonstrations and science fairs.

What is the percentage of iodine in potassium iodide?
The percentage of iodine in potassium iodide can be calculated using the formula: (molar mass of iodine / molar mass of potassium iodide) x 100. The molar mass of iodine is approximately 126.9 g/mol, and the molar mass of potassium iodide is approximately 166 g/mol. Therefore, the percentage of iodine in potassium iodide is (126.9 / 166) x 100 = 76.5%.
Why is potassium nitrate in toothpaste?
Potassium nitrate is added to toothpaste for its desensitizing properties. It helps to reduce tooth sensitivity by blocking nerve signals in the teeth, making it an effective ingredient for people who experience discomfort from hot or cold temperatures.
Potassium iodide plus lead nitrate?
When potassium iodide is mixed with lead nitrate, a double displacement reaction occurs. The products formed are lead iodide and potassium nitrate. Lead iodide is a yellow precipitate that forms during the reaction.
What is the ratio of potassium ions to iodide ions in KI?
The chemical formula of potassium iodide is KI The molecule contain 1 potassium atom, 1 iodine atom; the ratio is 1.
