Experimental Analysis of Hydrogen Peroxide Related classical Chinese
I have heard of the experience of analyzing hydrogen peroxide. The method is exquisite and the principle is profound.
At the beginning, prepare all utensils to make them clean and good. Take the liquid of hydrogen peroxide, measure it in a cautious state, and inject it into a specific device. In the meantime, observe its color, clear and transparent, without variegated stains; observe its shape, static and stable, without fluctuations.
Then, apply medicine to promote its change. When the medicine enters the liquid, there is an effervescent surge in an instant, like a spring gushing in the ground, the sound is small and the gas is vigorous. This is the image of the decomposition of hydrogen peroxide. Oxygen escapes outside, and water remains inside.
Record the number of bubbles, to measure the speed of decomposition. Time-shifting and speed varies, and at the beginning the speed is fast, like a gallop of a galloping horse, and it gradually slows down after a while, like the steps of a tired horse. Examine the time and speed in detail, draw a chart, its shape is like, and the law is self-evident.
Re-study its qualitative change. According to other things, observe its contact with hydrogen peroxide. Or color change, or temperature change, are all signs of its nature.
After the test, sum up the data and analyze the reason. To understand the cause of hydrogen peroxide decomposition, know the reason that affects its change. Or the amount of medicine, or the degree of temperature, are all key.
This experience is also a great contribution to the exploration of reason. It makes us understand the wonders of material change and the mystery of natural laws, which can be the foundation of future research and the way to knowledge.
