Well, darling, when you toss copper into salt water, you're starting a little chemistry show. The salt water acts like a stage manager, pulling electrons from the copper and causing it to corrode and turn green. It's like Mother Nature's version of aging gracefully, but with a bit more drama.
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.
When copper chloride is put into water, it starts dissociating. The molecule of copper chloride breaks up to give a cuprous ion(Cu2+) and 2 Chloride ions(Cl-). The water molecules weakly dissociate to give hydrogen ions(H+) and Hydroxyl ions(OH-). The oppositely charged ions interact and form a weak bond known as hydrogen bond. This interaction results in the copper chloride dissolving in the water.
When NaCl (salt) is added to carbonated water, the salt dissolves into its ions (Na+ and Cl-) without any significant reaction with the carbonation (CO2). The salt simply dissolves in the water, adding a salty taste.
Salt dissolved in water forms a solution. A solution is a homogeneous mixture where the solute (salt) is evenly distributed in the solvent (water) at a molecular level. Each component retains its properties and can be separated through physical means.
Silver has a higher reduction potential than copper (ie silver "wants" to be in reduced form - metalic form - "more" than copper does). If silver METAL (Ag0) is added to a solution of CuSO4, nothing happens since silver is already reduced and it wants to stay that way.
Electrolysis
It floats.
They die
When you put coins in salt water, a chemical reaction will occur between the salt (sodium chloride) and the metal in the coins. This reaction can cause the coins to corrode and develop a greenish patina over time.
they will die
The volume remain unchanged.
The concentration of salt increase up to saturation.
You can step on them or place them on copper or put them in a cup with hot salt water and shake.
Salt will dissolve in water. Adding salt will lower the temperature of water by a few degrees Celsius as well as lower the freezing point.
1 take the mixture of salt and sand and immerse them in water. 2 run the water and sand through a filter that separates out the sand. 3 store the sand. 4 boil the water until it has all evaporated or just wait for it to evaporate naturally. This will leave a residue on the bottom of the container which Will be the salt
adding salt raises the boiling point of water which can help speed cooking time.
Nothing...they die....
