Potassium Iodide Hydrogen Peroxide Experiment
Experiments on Potassium Iodide and Hydrogen Peroxide
At the beginning of the experiment
There were good researchers in the past who wanted to study the reaction between Potassium Iodide and Hydrogen Peroxide. It is to concentrate and prepare all the things. Put a clean utensil on the case, measure an appropriate amount of potassium iodide solution, and observe its color and purity, like the clarity of a clear spring. Also take a hydrogen peroxide solution, its state is stable, but it contains chemical mysteries.
At the beginning of the reaction
The potassium iodide solution is slowly poured into the vessel containing the hydrogen peroxide solution. At first, the liquid surface is calm, as if it were still water. Then, there are bubbles that rise slightly, like a spring pond and swamp melting, and the bubbles gradually increase, like strings of pearls gushing out from the bottom of the water, breaking the calm. At this time, when you smell it carefully, there seems to be a faint smell escaping, which is a sign of the formation of new substances during the reaction.
The reaction is not long
, and the reaction intensifies, and the bubbles are like boiling soup surging, soaring up, like a rushing spring. The wall of the vessel gradually feels warm, and when you touch it with your hand, the warmth gradually thickens, and this reaction is exothermic. Looking at its color, or because of the reaction products, it is slightly yellowish, just like the twilight afterglow, adding a touch of mystery to this wonderful change.
At the end of the reaction
After a little longer, the generation of bubbles gradually slows down, like a river returning to the sea, and becomes calm. Looking at the solution again, the color gradually fades, returning to nearly the original clarity. The reaction product lies quietly at the bottom of the vessel, as if telling the story of this wonderful change. Good researchers scrutinize the records to study the mechanism, rate and characteristics of this reaction, hoping to increase knowledge and add a ray of wisdom in the field of chemistry.
