🥳What we do?

    In 2022/11/28, we watch a video about acids and bases. The video is as follows:


🥳Summary

    In our daily life, acids and bases have many useful function. For example, they are been used to make food. Other examples like soap,  fertilizer, and even paper. At the greek, acids and bases had been defined by their behave. Acids tasted sour, and bases felt slippery and can conterout acids. In nowadays, acids and bases are difined with hydrogen atom.
    When we put acids and bases together, "neutralization" will appear. As neutralization occurs, the hydrogen atom of acid will plus the hgydroxide which come from bases, them a water molecular appears. Water is just like a banker, who balenced acids and bases. 

🥳Our experience of the video

    Acid-base is not only knowledge in chemistry textbooks, but also closely related to human life. For example, the stomach secretes hydrochloric acid for digestion and sterilization. Some fertilizers contain alkaline substances such as calcium carbonate that can be used to improve acidic soil... These functions are very common in life. From a microscopic point of view, scientists have put forward many explanations for these magical reactions, even in ancient Greece, as mentioned in the video: acid tastes sour, corrodes metals; Alkaline substances feel smooth and can neutralize acid. It can be seen from here that acids and bases can neutralize each other, which is a microscopic explanation of the relationship between protons or electron gains and losses. It is often called Reduction-oxidation reaction. This video allows non-professionals to understand the far-reaching impact of acids and bases in life, and also popularizes chemical expertise in a simple way.
