The change of copper and yellow in peroxygenation
The things in the world, when they meet, sometimes they change for no reason. Today there is dioxy water, which is lively in nature, and strongly oxidizes and can erode. There is also a brass tool, which is yellow in color and strong in quality, which is commonly seen by the world.
When dioxy water meets brass, its scene is very different. Dioxy, $H_ {2} O_ {2} $Also, it contains active oxygen, which is released when it encounters brass. Brass, an alloy of copper and zinc, zinc is active, and it encounters dioxy first.
At the beginning, there is a slight blue in the liquid, and there seems to be a bubble that is about to emerge. After a while, the bubbles gradually flourish, like beads gushing out. Dioxygen decomposes, oxygen escapes outside, and in brass, the oxygenation of zinc and dioxygen gradually becomes invisible.
After a while, the color of brass gradually changes, and it is no longer golden as it used to be. The gradual disappearance of zinc makes it difficult for copper to exist in its own state. When copper encounters oxygen from dioxygen, it turns into an oxide of copper, and the color turns dull. The color of the liquid also changes slightly, either light green or slightly yellow, because copper ions dissolve into it.
Looking at this change, we can see that the physical properties are in phase, and the physical phase is sensitive. The strong oxygen of dioxygen can destroy the strength of brass and change its shape and color. Although this ordinary thing meets, the principles in it are enough for scholars to learn from, so as to understand the way of change of all things.
