雞蛋浸入醋中時,雞蛋周圍出現很多小氣泡,小氣泡是______

the egg shell is made of mineral salt, mainly calcium carbonate, plus some protein structure so that the mineral can form according to the shape.

2) on the surface, acid plus carbonate will give you CO2, the corresponding salt and water. For the egg white, it will de-nature the protein structure, may break some bond in the protein. for the egg yolk, emulsion will take place, which will make the egg yolk more soluble.
Chemical formula:
2 CH3COOH + CaCO3 = H2O + CO2 + Ca(CH3COO)2.

小氣泡是CO2,即二氧化碳(carbon dioxide)

carbon dioxide 二氧化碳
