Metals higher in the reactivity series displace metals that are lower down. This concept has wider application than simply metals.
Usually.
The chemical reaction is:Cu + 2 AgNO3 = 2 Ag + Cu(NO3)2
The solute is Urea, and one of the solvents would be alkali metal nitrates
RbI + AgNO3 ---> RbNO3 + AgI It is displacement reaction. Rubidium is an alkali metal hence it is highly reactive and easily displaces silver from silver nitrate solution.
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.
I think you mean displacement reactions. There are 2 types of displacement reactions: single, and double displacement. Single displacement is when a metal -nonmetal reacts with a metal or a nonmetal atom, and the metal or nonmetal atom switches places with the one in the molecule. Double displacement is when two molecules (same as above) react, and the metals/nonmetals (it doesn't really matter in this case) are swapped. They both have a switching of places between atoms, so I guess this is how they are similar.
What is the metal cation that gives the 'green' colour.
Examples are: nitrates, chlorides, sulfates, phosphates and many other.
Metals undergo neutralization reactions with acids. The products of these reactions are a salt of the metal and the gaseous hydrogen. Direct addition of metal to an acid solution may cause explosions as they are highly exothermic.
Nitrates are used as sources of metal ions because all metal nitrates are soluble in water. This is very useful for metals such as lead and silver whose compounds are usually insoluble.
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
- the color of the solution is changed- the displaced metal is precipitated
it displaces the less reative metal and replaces it.
Yes. The magnesium metal replaces the copper in the copper sulfate. This is a single replacement or single displacement reaction.
Any metal more reactive than copper can be the replacing metal in copper sulfate solution reactions. Iron and zinc are the most common metals replacing copper in these reactions.
