What happens when you mix hydrogen peroxide with potassium iodide?

What happens when you mix hydrogen peroxide with potassium iodide?

The potassium iodide is added, and the iodide ion that’s part of that compound attracts the oxygen in the hydrogen peroxide, breaking the bonds and rapidly transforming the hydrogen peroxide into water and oxygen gas. The oxygen molecules then get trapped by the soap, forming bubbles, Hostetler said.

What type of reaction took place in between hydrogen peroxide and potassium iodide?

Brief Description: Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste. This is the classic “Elephant Toothpaste” reaction.

What happens when you mix hydrogen peroxide and sodium iodide?

The sodium iodide reacts with the hydrogen peroxide (H2O2) by removing an oxygen atom. This essentially produces water and oxygen gas (H2O + O2). The oxygen gas produced gets trapped in the soap which produces the big ball of foam. The reaction produces oxygen gas, water and iodine.

What is the equation for Elephant Toothpaste?

Overall Reaction: 2 H2O2 (aq) → 2 H2O (l) + O2 (g) Page 2 NCSU – Dept. of Chemistry – Lecture Demonstrations Kinetics Safety: Wear proper protective equipment including gloves and safety glasses when preparing and performing this demonstration.

How do you make Elephant Toothpaste?

Make Elephant Toothpaste Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Swish the bottle around to mix the ingredients. Set the bottle in a sink or outdoors or some other place where you won’t mind getting wet foam everywhere.

When hydrogen peroxide solution reacts with iodide ions in aqueous acid iodine is liberated?

When hydrogen peroxide solution reacts with iodide ions in aqueous acid, iodine is liberated. H2O2(aq) + 2 H+(aq) + 2 I–(aq) → 2 H2 O(l) + I2(aq) The following table gives some experimental results for the reaction.

How hot is elephant’s toothpaste?

The 500 ml of water has a heat capacity of around 2100 J/K. So, the solution gets about 12 K hotter. This calculation seems to assume 3% hydrogen peroxide. A good elephant-toothpaste demo will use 30%, which of course produces ten times the energy.

What happens when hydrogen peroxide reacts with aqueous KI solution?

The reaction is as follows: H2O2+2KI+2H+→I2+2H2O+2K+

Which of the following statement is correct when hydrogen peroxide reacts with acidified potassium iodide solution?

Answer: Reaction 1: Acidified hydrogen peroxide will react with potassium iodide solution to produce a brown solution.
