What happens when you mix hydrogen peroxide and potassium permanganate?
When you add the potassium permanganate, it reacts with the hydrogen peroxide to produce oxygen in small “pockets”. These pockets of oxygen increase the intensity of the reaction and you get the cannon fire noise as the pockets of oxygen hit the flame.
How can you explain diffusion using potassium permanganate?
Potassium Permanganate Diffusion in Water Place the crystals at the bottom of the beaker. Steadily add distilled water to the beaker up to 35 milliliters or so of volume. Because of the random movement of potassium permanganate particles, a dense purple solution forms in water at base of the beaker.
What happens when potassium permanganate is added to water?
a) When potassium permanganate crystals are placed in hot water, the solution turns to purple in color because of a process called diffusion. Diffusion is the movement of molecules or atoms from high concentrated region to low concentrated region.
What happens when potassium permanganate is added to cold water?
Expert-verified answer When a piece of Potassium permanganate (KMnO₄) is added to or placed at the bottom of a beaker which contains cold water, then the water turns into a purple coloured solution.
What happens when you mix vinegar and hydrogen peroxide?
Hydrogen Peroxide + Vinegar Combining them creates peracetic acid, which is potentially toxic and can irritate the skin, eyes, and respiratory system.
What happens when you mix baking soda with hydrogen peroxide?
The Hydrogen Peroxide and Baking Soda Reaction The exothermic reaction generates and releases a minor amount of carbon dioxide gasses. As the gasses are released, the mixture neutralizes and becomes completely water-soluble.
Why does potassium permanganate diffuse faster than methylene blue?
There is a substantial difference in molecular weight between Methylene Blue (320 g/mol) and Potassium Permanganate (158 g/mol). The combined molecules present in Potassium Permanganate are lighter than those in Methylene Blue, and therefore should allow it to diffuse more rapidly.
Why does potassium permanganate diffuse faster in hot water?
Molecules move faster at higher temperatures, so the higher the temperature (the warmer the water), the faster potassium permangnate will diffuse into the water.
Why is potassium permanganate used in water diffusion experiment?
Potassium Permanganate is approximately half the molecular weight of Methylene Blue and diffuses more rapidly than Methylene Blue, resulting a slightly larger radius for the Potassium Permanganate dye spot than for Methylene Blue.
How does temperature affect the rate of diffusion of potassium permanganate?
When the temperature of the water with potassium manganate crystals in increases, the particles in the water and crystal will then speed up and move around more quickly. Therefore it will take less time for the purple colour to spread out.
