鉴别试验( 1 )本品的水溶液( 1+1000 )呈现带蓝光的红色。( 2 )取本品的水溶液( 1+1000 ) 5ml ,加盐酸 1ml 时,产生蓝光的红色沉淀。( 3 )本品的硫酸溶液( 1+100 )显黄褐色,取此液 2-3 滴,加到水 5ml 中时,产生带蓝光红色沉淀。( 4 )取本品 0.1g, 加乙酸铵溶液( 3+2000 ) 200ml 溶解,取此液 1ml ,加乙酸铵溶液( 3+2000 )配至 100ml 的溶液,在波长 546-550nm 处有*吸收带。
Identification test (1) the product of the aqueous solution (1 + 1000) presents the red with blue light. (2) take this product aqueous solution (1 + 1000) 5 ml, add 1 ml of hydrochloric acid, produce the blue red precipitate. (3) the product of the sulfuric acid solution (1 + 100) tan, take this 2-3 drops of liquid, add to the water 5 ml, produce with blue light red precipitate. (4) get a 0.1 g of the product, and ammonium acetate solution (3 + 2000) 200 ml dissolved, take this liquid 1 ml, adding ammonium acetate solution (3 + 2000) to 100 ml solution, 546-550 - nm wavelength in place have the largest absorption band.
