The volume of the solution will NOT be the same after salt is dissolved. In fact, in a saturated solution of NaCl, the volume actually goes DOWN slightly. The explanation is too complex for this discussion. Some salts will increase the volume. You may not notice the change, and it will depend on the amount of salt added. The more salt, the greater will be the change in volume.

∙ 6y agoBecause the salt dissolves into the water rather than displacing it. In other words the density of the salt water is greater than the fresh water. Remember density is mass per unit volume, so by dissolving the salt into the water you are increasing the mass at constant volume.

∙ 14y agoSince the salt becomes part of the water, and doesn't take up space in the water, the water level doesn't change.

∙ 13y agoBecause the salt falls apart in chloride and natrium ions, that settle in the free spaces between the water molecules.
Wiki User
∙ 13y agoBecause the salt is absorbed the water, and the salt also takes up less volume than water does, so the water level will decreased..

This is because the NaCl or sodium chloride or salt molecules occy the spaces between the water molecules.

How do you separate salt and water after the salt is dissolved?
You get two cups then you put your hand on the cup that has the water and the salt and pour it and there it is
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.

What physical process makes salt decrease in salt water?
Adding more water will decrease the salt concentration.
Will the temperature of a beaker of water increase or decrease when it is mixed with sodium chloride?
Dissolving salt in water is mildly endothermic; therefore, the temperature of the sytem as a whole will decrease. Please see the link. +++ An intriguing effect occurs if you pour salt into melting ice: the temperature drops considerably.
What is the effect when you pour salt on a plant?
If the plant is not a salt water plant, then plasmolysis will occur when you pour salt on a plant.When you pour salt on a plant water molecules inside the cell are drawn out. When the water molecules leave the cell, the cell becomes dehydrates and shrinks. This is called plasmolysis.
What are materials used for separating salt and sand?
Water and a filter would work. Pour the salt/sand into water and the salt will dissolve. Pour the mixture into a filter and the sand will be trapped in the filter. Evaporate the water and the salt will remain.
How do you dissolve?
1.get salt 2.get water 3.pour salt into water 4.stir the salt and water until the salt is invisible

Will turgidity carrot cells in salt water increase or decrease?
Turgidity will decrease in salt water because water in the carrot will flow out in order to try to equalize the high concentration of salt.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
How does salt affect the water's melting point?
Adding salt to water the freezing point decrease.
Since salt dissolves in water does this decrease its density?
Salt water will be more dense than the water, but less dense than the salt.

salt water
