279强蛋白银ARGENTO-PROTEINUM FORTE1)本品鉴别之(1):取本品约0.2g,置磁坩埚中,炽灼,灰化后,加硝酸1ml,加热,使溶解,溶液中,加蒸馏水10ml 与盐酸数滴,即生成白色的沉淀,能在(?)试液中溶解。说明——本品含有蛋白质,因此加热时,发生特异臭,炽灼的灰分。主要为金属银,加硝酸加热溶解后,生成硝酸银,加盐酸发生氯化银沉淀,此沉淀加氨试液,生成可溶性络盐而深解。AgCl+2NH_4OH→Ag(NH_3)_2Cl+2H_2O2)本品鉴别之(2)取本品的水溶液(1∶100),
279 strong protein silver ARGENTO-PROTEINUM FORTE1) Identification of this product (1): take this product about 0.2g, set the magnetic helium, ignition, ash, add nitric acid 1ml, heating, so that the solution, add distilled water A few drops of 10ml and hydrochloric acid produced a white precipitate that dissolved in the (?) test solution. Explanation—This product contains protein, so when it is heated, a special odor and flaming ash occur. Mainly metal silver, plus nitric acid heating dissolved, the formation of silver nitrate, hydrochloric acid chloride precipitation occurs, this precipitation plus ammonia test solution, resulting in soluble complex salt and deep solution. AgCl+2NH_4OH→Ag(NH_3)_2Cl+2H_2O2) Identification of this product (2) Take an aqueous solution (1:100) of this product,
