May I answer it in english?It will dissolve in water because there is mostly calcium carbonate(CaCO3) in pearl which will react with the ethanoic acid(CH3COOH) in vinegar to form calcium ethanoate (CH3COOH)2Ca which is soluble in water

珍珠又名真珠, 乃蚌屬所生的圓珠,色白如銀,為貴重的飾物。有關珍珠的用途,據了解是屬於中藥的一種,要把它磨碎成為粉狀,具有養顏及可以作為嬰孩定經或鎮定劑之用;相信該珍珠粉末,當服食後會被胃酸所溶化而被胃腸所吸收。
