Does Boiling Water Remove Sodium/Salt from Water at Home? FIND OUT!

Spread the love

Boiling water does not remove sodium, salt or any nutrients, in fact, the boiling process reduces water thereby increasing the salt concentration within the cooking unit.

As soon as the water get heated up to the point of evaporation, the water is reduced within the vessel and the salt level is increased instead.

Salts like some minerals features higher boiling temperature and this remain within the substance/vessel. In other words, boiling water that contains salt will make it even saltier, as the ratio between water and sodium is changed in favor of the sodium.

Does Boiling Reduce Sodium Content in Drinking Water?

Boiling water WILL NOT reduce the sodium in drinking water. Sodium is a dissolved metal. Instead, boiling water vaporizes it, and sodium has much higher boiling point than water, and that will only increase the salt content if you continue to boil for longer.

Distillation is the process by which you can reduced the salt content of the boiled water.

How to Remove Sodium Chloride (Salt) From Water At Home

You can use the following to remove sodium from water::

  • Reverse Osmosis (the most economical) (CHECK ON AMAZON)
  • Electro dialysis,
  • Distillation techniques or
  • ion exchange. Reverse osmosis is most economical considering energy and money requirements.

Remote areas, Islands, or places with no freshwater available turn to certain means to get fresh water from plants. Reverse osmosis is one of the techniques; this method uses pressure to force water through various membranes that block the unwanted minerals and other molecules from going through desalination plants.

This, however, is an expensive process and needs a bit of investment, here are some additional cheaper alternatives to removing sodium from water:

  • Water distiller

Water distillation is a process of salt removal that involves boiling and capturing all the evaporated water (steam) and letting them condense back into a liquid state. It is commonly used on an industrial scale for processes that need pure water.


However, as a residential owner or business owner, we recommend investing in a countertop distiller – available in different sizes and shapes. A countertop distill will distill around a gallon of water at a time and is compact so storing won’t be a problem.

  • Solar still

Living in an Isolated place without electricity? Solar distillation is the way to go! These devices will harness the sun’s power to evaporate the water and therefore might not work best on cloudy days or in colder climates.

There are fairly simple to create with some regular household materials, or are available for order online.

  • Freezing water

This process removes salt from water without having to reply on heat.

Salt reduces the freezing point of water, so, as water begins to freeze, the salt becomes concentrated in the fluid part. If you place a container of salted water outside a cold area or in a freezer after a while ice will begin to form.

The ice contains a reduced amount of salt that allows it to freeze before the saltier water does. By collecting the ice before the whole container is frozen solid you are able to separate the water with a lower salt concentration and melt it for use.

This process is not 100% effective and depending on the application and initial salt concentration you might have to repeat the process several times for the desired result.

Keep in mind that you have to start with a significantly larger amount of water as in each cycle a large portion will have to be discarded.

  • Dilution

Lolz, this doesn’t actually remove the salt, but depending on the use, it might just work! Assuming you have a saltless water available, you can dilute it to reduce the taste of sodium in it.

  • Buy Bottled (distilled) Water

I know this might not be one of the options you want to hear but if there is a chance you might be stranded on a tropical island then there is no reason of gambling on whether there will be fresh water or not. Just drop by your local store, or go online and order some bottled or distilled water.

Does Drinking Water have Sodium?

Yes, drinking water from public tap water does contain small traces of sodium, just not enough to have adverse effects on your system.

Does Zero Water Remove Sodium?

Yes, zero water removes sodim since salt is TDS and it brings TDS’s to zero I would say yes.

Does Boiling Tap Water Remove Minerals or Destroy Nutrients?

Like boiling salt, boiling tap water DOES NOT REMOVE any other minerals from the water. In reality, there is no actual nutrients in drinking water.

The minerals that might possess some nutritional value are not destroyed by boiling as they stay dissolved through the boiling process.

The main reason why some bottled water contains adjusted amounts of minerals is because of the taste.

Do Refrigerator Water Filters Remove Sodium?

Refrigerator water filters does not remove sodium or heavy metals unless your refrigerator specifically lists them.

Boiling vs Filtering Tap Water

Normally, most tap water does not need boiling or filtering before you can consume. However, contaminations have been reported to occur in some cases and it would be wise to take the necessary precautions.

Although there isn’t any disadvantage to drinking boiled water, the benefits include a quick kill of bacteria and every pathogen. However, even dead these things will remain in your water.

As earlier stated, boiling water might kill but does not remove any undesired minerals or toxic metals from within the water. If you have reasons to believe that your water might be contaminated then you should consult an expert and look into taking precautions like a water filter or reverse osmosis installation.

Keep in mind that no system is perfect, and in case of doubt your safest bet will probably be bottled water.

Are There Benefits to Low Sodium Water?

While there are health risks to consuming extreme amount of sodium diet, you’re most unlikely to be affected by your current intake.

Even in the most extreme cases, with water hardness levels of over 400mg/L of calcium bicarbonate, softened water will at most contain 200 mg/L of sodium.

This means you would have to consume 11.5 liters or more than 3 gallons!! of water every single day to exceed the recommended daily sodium intake of 2,300mg.

This of course doesn’t take into account any sodium intake through other means like food; however, the average American has an intake of 3,400 mg of sodium a day.

At a more reasonable water hardness level (around 100 mg/L of calcium bicarbonate) your daily water consumption would need to be more than 45 liters or 12 gallons per day. At those levels, the real danger would most certainly be water poisoning.

Does Boiling Chicken Reduce Sodium?

Boiling chicken does not reduce sodium. However, boiling thawed chicken breasts in unsalted water with a coarsely chopped, peeled potato helps concentrate sodium in a way that you can easily get rid of it.

Does Fresh Chicken Have Sodium?

No, raw fresh chicken does not sodium. However, some people might add as little as 50-75 milligrams of sodium per 4-ounce serving.

Does Cooking Reduce Sodium?

Cooking does not reduce sodium, instead it increases salt levels. Roasting, grilling, roasting, searing and sautéing bring out natural flavors, not reduce sodium.

What Removes Sodium from Water?

Reverse osmosis is a highly natural and effective means of sodium removal from softened water. Plus, it reduces the amount of water contaminants too.

Does Boiling Water Reduce Salt?

Boiling water does not reduce salt or remove sodium. Instead, it will only increase concentrations.

What Happens to Sodium In Boiling Water?

The sodium in boiling water dissolves and breaks down into chloride and sodium ions. Once the water is completely boiled off, the ions would recombine to form solid salt.

Is it Healthy To Salt Pasta Water?

It is safe to salt pasta water as far as you’re salt tolerant. You can do 1/16 teaspoon per 4-ounce serving or a total of 1/4 teaspoon per pound of pasta.
