　　02、中學部科學俱樂部創(chuàng)意：通過化學反應雕刻雞蛋

　　同學們取出一顆雞蛋，洗去表面油污、擦干。用毛筆蘸取醋酸，在蛋殼上寫字。等醋酸蒸發(fā)后，把雞蛋放在稀硫酸銅溶液里煮熟，待蛋冷卻后剝去蛋殼，雞蛋白上留下了藍色或紫色的清晰字跡，而外殼卻不留任何痕跡。原理：這是因為醋酸溶解蛋殼后能少量溶入蛋白。雞蛋白是由氨基酸組成的球蛋白，它在弱酸性條件中發(fā)生水解，生成多肽等物質，這些物質中的肽鍵遇Cu2+發(fā)生絡合反應，呈現藍色或紫色。

　　Students took out an egg, washed off the surface oil, dried it. Dipped the brush in acetic acid and wrote on the eggshell. After the acetic acid evaporates, the eggs were boiled in a dilutecopper sulfate solution. When the eggs were cooled, peeled off the shell. Clear blue or purple writing was left on the white of the egg, but no trace of the shell was left.

　　How it works: this is because acetic acidcan dissolve eggshells in small amounts. Egg white is a globul in composed of amino acids, which hydrolyze in weak acidic conditions to produce polypeptides and other substances, the peptide bonds of these substances meet Cu2+ complexreaction, show blue or purple.
