雞蛋加白酒
發問:
雞蛋加白酒放到玻璃杯, 白酒浸過雞蛋, 1.有什麼發現? 然後用塑膠包起杯口, 放幾日,拿出來, 2.雞蛋會出現什麼變化? 更新: Sor,打錯係雞蛋+醋
無什?變化 , 因蛋殼含碳酸鈣 , 而白酒內酒精又不會與蛋殼發生化學作用 , 而酒精有殺菌作用 , 可保持蛋不變 . 2009-09-08 17:55:21 補充： 如果是醋就不同了 , 蛋穀含CaCO3 which is dissolved by vinegar(5-9%acetic acid) to for calcium acetate . So the acetate is dissolved in water & now the egg is enclosed by a soft layer of proteneous layer . 2009-09-08 17:57:38 補充： "to form calcium acetate " miss "m"
其他解答:
vinegar is an acid egg shell is mainly made of calcium carbonate(CaCO3) since acid will react with CaCO3 CaCO3 will dissolves in the acid so the egg shell with look like dissappeared
