Distilled water is a process of heating water to create steam which is then left to cool and convert back to water. It is salt and mineral free. Distilled water has plenty of practical uses. It features in steam irons and car batteries. It helps to stop iron’s getting clogged as a result of mineral build-up. It has several industrial and medical uses. Distilled water is great for making clear ice cubes.
Steps to make distilled water in the home
- 3-5 gallon pot and cover (stainless steel)
- Regular tap water
- Baking tray
- Heat-resistant bowl (glass)
- 1 – Place the stainless steel pot on the baking tray
- 2 – Pour tap water into the pot to the halfway point
- 3 – Place the heat-resistant bowl in the pot – it should float on the surface
- 4 – Position the pot cover on top of the pot in an upside down position
- 5 – Place the ice into the inverted pot cover
- 6 – Heat the water and bring to boil for approx 45 minutes, replace the ice as and when required. The boiled water converts to steam. The steam is cooled by the pot cover and turns back into water. The water that drips into the bowl is the distilled water.
- 7 – Switch off the heat. Take the lid of the pot. Use safety gloves to remove the glass bowl; this is now very hot.
- 8 – Leave the distilled water to cool and place in suitable bottles for storage.
Understanding the pH of Distilled Water
Any solution with a low-pH is termed as acidic and a high-pH is basic. Preferably, distilled water should be neutral, with a pH of 7.
The distillation process
The process to distill water is simply to boil the water and transfer the stream into a separate container. The steam cools and reverts back to liquid. This process produces pure water with all imperfections left behind. However, distillation isn’t able to remove alcohol or other solutes that evaporates with the water. Any water with alcohol will need further refinement to cleanse the water.
Another simple way to make distilled water at home
If you think the method used to distilled water above is a little complicated, you can buy a countertop water distiller to make the whole distillation process much easier and you can use it to make distilled regularly and conveniently.
How does distilled water absorb Carbon Dioxide?
Pure, distilled water has a pH of 7 and isn’t seen as alkaline or acidic. Once the distillation process is complete, the water starts to take in carbon dioxide from its surroundings. This can lead to the formation of a weak acid known as carbonic acid. The process of absorbing carbon dioxide continues until the amount in the atmosphere and the water is equal. On reaching this point, the distilled water has a pH of about 5.8.
