When a certain amount of iron powder is added to the mixed solution of Cu (NO3)2, AgNO3 and Zn (no3)2 and bubbles are generated, the filtered solids must contain? The filtrate must contain? (Fill in chemical formula)
The topic is incomplete,
When a certain amount of iron powder is added to the mixed solution of Cu (NO3)2, AgNO3 and Zn (no3)2, and the iron powder is filtered after sufficient reaction, the filter residue is dripped with dilute hydrochloric acid, and bubbles are generated, the filtered solid must contain certain solutes contained in the AgCuFe filtrate as Zn (NO3)2 and Fe (NO3)2
The topic is incomplete,
In the mixed solution of Cu (NO3)2, AgNO3(NO3)2, AgNO3 and Zn (no3)2, the filter residue is added with dilute hydrochloric acid after full reaction, and bubbles are generated, the filtered solid must contain certain solutes in the AgCuFe filtrate as Zn (NO3)2 and Fe (NO3)2

Add a certain amount of iron powder to the mixed solution of AgNO3 and Cu (NO3)2. After the full reaction, metal precipitates out. Filter, add dilute hydrochloric acid to the filtrate after washing, and colorless gas is released. The solute in the filtrate must be () A. Fe (NO3)2 B. Cu (NO3)2 and Fe (NO3)2 C. AgNO3 and Fe (NO3)2 D. AgNO3 and Cu (NO3)2
It can be seen from the metal activity sequence table that in the metal activity sequence, iron > hydrogen > copper > silver. When dilute hydrochloric acid is added to the filter residue and colorless gas is released, it means that the filter residue contains iron. Iron can react with silver nitrate to form ferrous nitrate and silver nitrate, and react with copper nitrate to form ferrous nitrate and copper nitrate. When there is iron residue, it means...
