The process of converting salt water to fresh water is called desalination and there is a lot of information on the subject.
Mother nature turns salt water into fresh water everyday by evaporation of water from the oceans. Clouds, with water vapor, water droplets and ice crystals form from evaporation. Then, it rains or snows nearly pure water/ice.
When humans artificially create pure water, the water is typically heated to drive the pure water off as water vapor and leave the salts behind. In chemistry, heating a liquid to vaporize it so that it condenses in a purer form is a process is called "distillation".
Another process, more specifically for water, is reverse osmosis filtration through a series of differentially permeable membranes allowing pure water to pass while trapping salts and other impurities. When any process is used to remove salts from seawater, the process is called desalination.

What is the principle of fresh water generator?
The principle of a fresh water generator involves the distillation process, where seawater is heated to produce steam, which is then condensed to yield fresh water. This process typically utilizes waste heat from engines or boilers to evaporate the seawater, separating salt and impurities. The resulting steam is cooled in a condenser, leading to the formation of distilled water, which is collected for use. This method is efficient and widely employed in marine applications and arid regions for freshwater production.
What is a suitable method for separating salt from seawater?
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
Why seawater has greater density then that of freshwater?
because it has a higher concentration of ions and minerals!!! ions and minerals play a vital role to make sea water more dense. secondly, the molecular mass: water: h(2) + o(16) = 18g/mol NaCl = n(23) + cl(35.5) = 58.5g/mol NaCl has a higher moleculer mass so there is higher density than water seen!
Why would it be better to use the muddy puddle water than the seawater?
It is better to use the muddy puddle water than the seawater because of the salt
What is the most dense pure water at 1 degree Celsius pure water at 4 degrees or seawater?
Seawater, then pure @ 4 degrees C.
What are the materials needed to obtain fresh water from seawater?
It will need a Reverse Osmosis membrane to filter out salts from the water.
What does curacao do to obtain fresh water?
Curaçao obtains fresh water primarily through desalination, a process that removes salt from seawater. The island has several desalination plants that convert seawater into potable water to meet its needs. Additionally, rainwater harvesting is practiced, where rainwater is collected and stored for use, although this source is limited due to the island's arid climate. Together, these methods ensure a reliable supply of fresh water for the population and tourism.
What is salt removed from seawater to obtain fresh water?
desalination de - undoing sal~ - salt; salin~ - having salt
Why is it easier to swim in seawater then it is to swim in fresh water?
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
How can fresh water be made from saltwater?
AnswerFreshwater can be made from seawater by a process called desalination.
Is the Gulf of Oman fresh water?
No, it is seawater.
How do you separate fresh water from seawater?
by evaporation
What is the concentration of salt in seawater and the specific heat capacities of sea water and fresh water?
the seawater smells
What is the process used to obtain water from sea water?
Desalination is the process used to obtain freshwater from seawater. This can be done through methods such as distillation or reverse osmosis, which involve removing salt and other minerals from seawater to make it safe for drinking or irrigation.
What happens when a ship sails from seawater to fresh water?
When a ship sails from seawater to fresh water, the buoyancy of the ship increases because fresh water is less dense than seawater. This can cause the ship to ride higher in the water. Additionally, there may be a slight increase in the ship's speed due to the lower density of the fresh water offering less resistance to the hull.
How do salts get removed from the seawater?
Salts are removed from seawater through a process called desalination. This can be done through various methods such as distillation, reverse osmosis, or electrodialysis. These methods help separate the salts from the water, resulting in fresh water that is suitable for consumption.
What is it called when fresh water meets seawater?
When fresh water meets seawater, it is called a "brackish water" environment. This occurs in estuaries or coastal wetlands where rivers flow into the ocean.
