Distilled Water faq
Distilled Water
The water which is almost completely pure and doesn’t contain any impurities can be roughly defined as distilled water. Boiling water and condensing the steam formed as a result of it, is known as distillation. Most of the impurities present in water are removed by the process of distillation. The information about what is distilled water and factors affecting its pH are provided in the following paragraphs.
What is Distilled Water
Rain water in its purest form can be called as distilled water. However, reaction with CO2 and pollutants results into rise in its acidity. The nitrous and sulfur oxides are converted into nitric and sulfuric acid respectively. Thus, by the time, rain water reaches the ground surface, it attains a yellowish tinge.
What is the pH of Distilled Water?
To know the pH of distilled water, one should first understand what exactly is pH? It is the measure which determines alkalinity or acidity of a particular solution The letter ‘p’ in pH stands for ‘potenz’, a German word. The English translation of potenz is power. The ‘H’ on the other hand means hydrogen. The hydrogen ‘power’ of a solution is thus, determined by means of pH. Ideally, the pH of distilled water needs to be 7. The pH of 7 indicates that, the liquid is neither acidic nor alkaline. The pH of distilled water that is prepared in laboratories is however, in the range of 5.5-5.8. This is because, it is very difficult to achieve a perfect 7 of pH, due to interaction with carbon dioxide (CO2). The reason behind it is that distilled water needed for practical application has to undergo interaction with the atmosphere. The interaction of distilled water with CO2 in air, results in the formation of carbonic acid. Thus, introduction of ions in the chemical composition/structure of water molecules results into the alteration of pH. Read more on how to make distilled water.
What is the Difference Between Distilled Water and Purified Water?
The difference between pure and distilled water is that, the former is prepared by filtering water while the later by boiling it. The process of filtration leads to removal of impurities up to a certain extent; it may contain naturally found minerals. Distilled water on the other hand doesn’t contain solid materials; So, "What is distilled water made of?" It is just pure hydrogen dioxide (H2O). Read more on distilled water vs spring water.
What is Distilled Water Used For?
Let us understand what is distilled water good for? One cannot judge as to, what is distilled water best used for. This is because, it serves many other purposes apart from the usage in laboratories i.e. in research projects.
* The distilled water is suitable for conducting experiments and also in cleaning purposes. As stated earlier, it is one of the most important applications of distilled water.
* The domestic use of distilled water is made for cooking. It can especially be used in the preparation of diets containing low amount of sodium.
* In the industrial areas, distilled water proves to be useful in developing photographic films. The reason behind using distilled water for this job is that photographic films have a layer of certain chemicals on them. These chemical are washed away and no other chemicals remain on the surface, if distilled water is used.
* Distilled water is also required for the purpose of filling wet-car batteries. Intravenous solutions too are prepared with the help of distilled water.

The article presented above gives us an idea about what is distilled water. The information about interaction of freshly distilled water with CO2 helps understand how the pH lowers down to the range of 5-5-5.8.
