Because iron is more reactive than copper. If iron displaces copper, that releases energy (enthalpy). If copper were to displace iron, that would require energy to be used. This is less favourable and , averaged over the huge number of molecules, atoms and ions in the solution, the more energy producing reaction is vastly preferred. Hence, iron put into copper sulphate solution gets coated in copper and the solution slowly loses its blue colour. But if you put copper metal in iron sulphate solution, nothing noticable occurs.
Iron is more reactive than copper, so when iron is added to a solution of copper salt, iron will displace copper by reducing it from its cationic form (Cu2+) to its elemental form (Cu). This is due to the difference in the reactivity series of metals, with iron being higher in the series than copper.
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
Some of the common species that can be present in aqueous solutions include water molecules (H2O), ions (such as H+, OH-, Na+, Cl-), and dissolved solutes (such as sugars, salts, and acids). The specific species present in an aqueous solution depend on the substances dissolved in the water.
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.
Insoluble salts are made through precipitation reactions between two soluble salts. This involves mixing two aqueous solutions of soluble salts to form an insoluble salt that precipitates out of solution. Common insoluble salts include silver chloride (AgCl), lead(II) iodide (PbI2), and calcium carbonate (CaCO3).
Yes, iron can displace copper from solutions of its salts through a displacement reaction. Iron has a higher reactivity than copper, so it can replace copper in the salt solution, forming iron salts and copper metal.
Then they would disolve in water, and would be useless in conjunction with aqueous solutions.
Aqueous salt solutions can have acidic or basic pH depending on the nature of the cation and anion in the salt. For example, salts of strong acids and weak bases (e.g., ammonium chloride) can create acidic solutions, while salts of weak acids and strong bases (e.g., sodium acetate) can create basic solutions through hydrolysis reactions. This leads to the pH of the solution being different from neutral.

Salts are obtained after the reaction of NH4OH with acids.

Nitrate is typically found in aqueous form as nitrates are highly soluble in water. Solid nitrates can form as crystals but are generally more commonly found dissolved in water.
Copper salts are chemical compounds that contain copper combined with other elements, such as sulfur, chlorine, or oxygen. They are commonly used in agriculture as fungicides, in pigments, and in various industrial processes. Some copper salts are also found in dietary supplements for their potential health benefits.
These salts are obtained from solutions evaporating the water.
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.

To copper coat iron powder, you can use electroless plating techniques where a reducing agent is used to deposit a layer of copper onto the iron powder. Another method is to mix the iron powder with a copper salt solution, followed by reducing the copper ions to form a copper coating on the iron particles.
