It is made of water (H2O) molecules and salt (NaCl) molecules. So two different types of molecules.

If you put 4 milliliters of salt into 50 milliliters of water why does the volume not increase by the amount you put in?
It's because the salt disolves into the water instead of adding more volume to it. The salt molecules are "taken apart" (dissociated) by the water molecules, and they are converted into Na+ and Cl- ions. These ions can fit "between" the water molecules, and can do so without increasing the volume of the solution. More salt can be added without increasing the volume, too. That is until saturation is reached, and then no more salt will go into solution. Adding additional salt beyond this point will increase the volume.
Is salt solution a conductor or insulator of electricity?
A salt solution in water is a conductor, due to the disassociation of the salt molecules into oppositely charged ions in the presence of the polar water molecules. A salt solution in a nonpolar solvent would likely be an insulator, as the salt molecules probably would not dissociate.
Does sugar dissolve quicker in salt water or soapy water?
Sugar would dissolve faster in soapy water. Sugar dissolving is actually the sugar molecules bonding with the water molecules. In salt water, sodium has already bonded with the water molecules, leaving no room for more bonding with sugar molecules. Soap, on the other hand, is a very mild base. It isn't so much a bonded element with water as it is a mixture. All of the water molecules are still available for bonding with sugar.
What does a dissolved salt look like?
The ions in the salt are surrounded by water molecules.
When a salt crystal is dropped into water the water molecules are attracted to the salt's ions and will surround them What is this called?
Hydration
What is the water made of?
Salt and Water. Molecules, too.
What is the sea water is made of?
Salt and Water. Molecules, too.
Why is salt not a molecule?
o “Salt water is full of sodium chloride molecules.” Salt is not made of NaCl molecules. Salt is made of a three-dimensional checkerboard of oppositely charged atoms of sodium and chlorine. More general ingredient: Sodium More specific ingredient: Chloride
When you add salt water to a carrot where is there a greater concentration of water molecules?
there is more water but not in the carrot and it isn't all fresh water but there is more water than salt
How do water molecules dissolves a salt?
The water molecules move around the salt ions In water, the salt separates into positive and negative ions.
Why does hot water dissolve more salt than cold water?
Salt dissolves quicker in hot water because the water molecules are moving faster than the cold water molecules, thus they have more contact with the salt molecules NaCl and break them up much faster.
Why can you add more salt to heated water before it saturates?
As water is heated, it expands. This larger volume means there's more room to fit salt in between the molecules. Also, the added heat energy allows the water molecules to fit between the ions in the salt more easily, pulling the salt into solution.
Why can you not see salt when it is dissolved in water?
because the salt molecules have mixed up with the water molecules
What is a soulution of salt water?
A solution of salt water consists of water and salt, the salt is made up of, if you are talking about common table salt, Sodium and Chlorine, which are separated from each other into individual ions by the individual water molecules. =)
What is a substance made up of two or more elements not combined chemically?
A couple of examples would be salt water and sugar water. The salt and sugar dissolve in the water, but still exist as smaller molecules (or in salt's case, as sodium and chlorine ions) among the water molecules.
Does cold water dissolve salt?
When substances have a high temperature, they have more energy. The more energy molecules have, the faster they move. The molecules in hot water move faster than cold water because of the higher energy. Because the molecules of hot water move faster, they can more easily break apart other molecules of a different substance when they come into contact. The fast moving water molecules can break apart the bonds between the salt crystals so they become dissolved into the water. Therefore, salt water can only dissolve in hot water.
