The egg is composed of three components viz. egg shell, egg white, egg yolk. Egg has rich protein and nutrient quantity. The egg when soaked in vinegar show physical change such that its shell becomes very soft to touch. This is due to the egg is put in vinegar; the calcium carbonate of the shell reacts chemically with the vinegar's acid. This reaction is named oxidation. In every chemical reaction, the initial substances disappear and they transform into new substances. After a few minutes we observe the formation of little bubbles, meaning a gas is being generated. It becomes just like a water balloon but the study says that it’s a rubber egg whereas the egg does not show any rubber like property. Finally, the egg increased in size because the liquid in the container has passed through the semi permeable membrane and has entered the egg. After the 24 hours we proved the egg bounces at different heights. Also study says that egg when placed in vinegar solution and after becoming soft it becomes hard when kept open to atmosphere but the experimental setup and the observation helps to prove this false. The egg vinegar also has many medical uses.The egg is composed of three components viz. egg shell, egg white, egg yolk. Egg has rich protein and nutrient quantity.
