Observe the diary - when the egg meets white vinegar

Thursday, October 20, 2019

I heard that the eggs will become softer in white vinegar and will become transparent. Is this really true? I decided to do it myself.

When I got home, I couldn't wait to open the freezer, carefully took out the eggs, placed them in a transparent cup, and slowly poured the vinegar. Hey, the egg was immediately surrounded by thousands of small bubbles, drifting a little bit, swaying, sinking, like a drunken drunkard. About a minute later, the egg slowly came out and revealed a small pointed tip of the size of the fingernail.

What does it look like? I went to bed the next day. I didn't wash my face and ran to see the eggs. It is still floating, but there is a brown film floating on it. Is this an eggshell? I took a closer look, the eggshell is still there! I gently touched it with chopsticks and scratched the surface of the eggshell to reveal the protein inside. I used chopsticks to continue to draw a famous name on the surface of the eggshell. The protein was more exposed, and the egg became a big flower face. White vinegar also became cloudy, I changed it to vinegar once.

Today, the egg gave us a transformation, the hard shell became a small broken foam, the small bubble is also small, the egg becomes transparent, like a crystal clear amber, and like a water balloon. I gently pressed it with my hand. It leaped like a naughty crystal baby, and like a ballet jumping on the water, sometimes jumping out of the water and sometimes sinking into the water.

I took the eggs out of the vinegar and carefully held them in my hand, for fear of breaking it. I carefully observed that the eggs became thin and transparent, as if they were blowing balloons, and the bombs could be broken. We can still see the egg yolk inside. I asked my mother: "Why does the eggshell become crystal clear?" Mom said: "The raw eggshell contains calcium carbonate, which reacts with acetic acid to form soluble calcium acetate and produces carbon dioxide gas." Tens of thousands of small bubbles are carbon dioxide gas. I also know that white vinegar soaked eggs can not only cure cough, but also beauty!
