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.
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.
Aqueous solutions are characterized by the presence of water as the solvent, which allows for the dissolution of various solutes, such as salts, acids, and sugars. These solutions exhibit properties like conductivity, depending on the concentration of ions, and can have varying pH levels based on the nature of the solutes. Additionally, aqueous solutions often have altered boiling and freezing points compared to pure water due to colligative properties. They also display osmotic pressure, which is essential in biological processes and industrial applications.
There will be no reaction if all the reactants and possible products are aqueous while there is no insoluble salts precipitate that are formed.
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.

Nitrates are salts and generally form stable solids, they are generally soluble and form aqueous solutions.
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.

Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
