2.NaNO3FeCl3AgNO3
分别有什么现象？谢谢回答！
刚入这行，谢谢大家
我想检测血管组织中的钙离子浓度，不知道哪个公司有试剂盒
A.H2SO4Na2SO4AgNO3BaCl2.
B.NaOHNa2CO3NaHSO4MgCl2
C.CaCl2NaNO3MgSO4BaCl2
D.HNO3KOHKClK2CO3
（1）优级纯试剂 亦称保证试剂，为一级品，纯度高，杂质极少，主要用于精密分析和科学研究，常以GR表示。
（2）分析纯试剂 亦称分析试剂，为二级品，纯度略低于优级纯，杂质含量略高于优级纯，适用于重要分析和一般性研究工作，常以AR表示。
（3）化学纯试剂 为三级品，纯度较分析纯差，但高于实验试剂，适用于工厂、学校一般性的分析工作，常以CP表示。
（4）实验试剂 为四级品，纯度比化学纯差，但比工业品纯度高，主要用于一般化学实验，不能用于分析工作，常以 LR表示。
以上按试剂纯度的分类法已在我国通用。根据化学工业部颁布的“化学试剂包装及标志”的规定，化学试剂的不同等级分别用各种不同的颜色来标志，见表1。
表1 我国化学试剂的等级及标志
C.MgCl2溶液和氨水D.盐酸和NaAlO2溶液
为什么
2.NaHCO3,Ba(OH)3,H2SO4
3.HCL,NaAlO2,NaHSO4
4.Ca(OH)2,Na2CO3,BaCO3
谢谢了
要原因
