The properties of water salts vary from one type to another. For example, solid salts that are considered dissolved in water contain a large number of invisible and inorganic components that dissolve quickly, in addition to other types of salts such as magnesium, sodium, calcium and potassium.
To know more details about the properties of water salts and how to measure them, we at Smartly will provide you with all the information you need within this article.
Properties of water salts
In general, it is easy for a person to recognize the properties of water salts, and in particular the physical properties of drinking water. Most of the properties have features on the basis of which water is rejected or accepted.
It is possible for the properties of water to change due to the presence of salts or natural or unnatural elements, which may change the nature, color and taste of the water in some cases, causing it to be unacceptable to people.
Properties and features of pure water
Pure water or water extracted from pure water filters would provide healthy water suitable for daily human use, and even for medical and pharmaceutical uses and for a large number of other uses.
One of the most prominent characteristics of pure water is that it is colorless, tasteless, odorless, and does not contain impurities, electrolytes, or microbes that are not visible to the naked eye.
There is no biological activity within this water and therefore in pure water filters, and specifically in the filters that we provide at Smartly. We guarantee the absence of germs and pollutants that are harmful to the health of living organisms in general, and the absence of harmful chemical pollutants.
Salts present in water
Dissolved salts in drinking water are the main component of the majority of dissolved solids, while these dissolved solids are ionic compounds that include a number of minerals in addition to other organic compounds and free metals.
Considering that the salts in which ionic elements are found are the most common in impure drinking water, it is possible to measure them to determine the concentration of dissolved substances. These salts consist of two parts, the first are positive salts that include sodium and potassium, while the other are negatively charged salts that include nitrate. , carbonate, sulfate.
This means that the total concentration of salts is determined by measuring positive and negative ions and studying the characteristics of each of them separately, as these salts mainly affect the taste of the water so that it becomes undesirable and unpalatable for drinking if the percentage of these salts increases.
How do salts get into the water?
Water often comes from rocks, soil, or groundwater in general, and salts can reach other natural water sources as a result of human activity, such as agriculture, industry, and other activities. A portion of these salts may actually be harmful, while some of them may be very little needed. For some specific uses.
While pure water filters and water desalination devices provide pure water suitable for various uses, including drinking, washing, bathing, medicine and industry, as it contains no pollutants, electrolytes and impurities and is in accordance with ideal health standards and standards.
Classification of water according to the concentration of dissolved salts
The characteristics of water salts, despite their diversity, determine classifications of water and facilitate the process for people who need pure water, of course. Here are the most prominent classifications of water according to the proportion and characteristics of water salts dissolved in it.
Fresh water
It is water in which the concentration of dissolved salts decreases to an extent that does not reach 1000 milligrams per liter of water, and fresh water itself is divided into two types: secondary fresh water, which contains dissolved salts at a rate between 500 to 1000 milligrams of salts, and pure water in which there is less Salt concentration of 500 mg per liter of water.
Medium salinity water: salty
The concentration of salts in this water ranges between 1000 and 5000 milligrams per liter, while salts may reach 1500 in some cases.
Salt water “brine solution”
The concentration of the properties of these water salts reaches about 35 thousand milligrams per liter of water, and the simplest and fastest example of them is sea water or salt serums that are widely used for medical purposes.
Ultra-salty water
The degree of concentration and characteristics of water salts here is very large and cannot be tolerated by any living organism. The concentration and characteristics of water salts in it reach between 35 thousand milligrams per liter of water and up to 70 thousand milligrams per liter, and if you are wondering about the presence of this super-salty water It is found in the Dead Sea specifically.
Unit of measurement for water salts
It is possible to measure the salinity of water and the percentage of salts present in potable water through an internationally approved unit of measurement, which is milligrams per liter. The normal rate for these salts is supposed to range between 300 and may reach more than 1000 milligrams per liter, but this percentage is certainly high. It does not include pure water, which is filtered and purified in special devices that ensure that impurities and electrolytes are completely absent.
Methods for measuring the concentration of dissolved salts in water
There are three common and main exhausting methods for measuring the concentration of dissolved salts in water in general and drinking water in particular. These methods are:
Electrical conductivity
Considering that dissolved salts in water are essentially ionic substances, there is a direct relationship between their high or low concentration on the one hand and the electrical conductivity of water on the other hand.
This direct relationship can be measured or expressed through the following equation:
Concentration of dissolved solids = constant x electrical conductivity of water
The determinants of this equation vary based on a special system that is followed to express the concentration of dissolved salts in water, while there are special determinants and ratios that are considered a basic and main criterion in each of the characteristics of the previous equation.
There are many laboratory devices that water purification and desalination companies rely on to determine the percentages of measuring dissolved salts, purify them, and provide users with pure water.
Gravimetric method
This method is also considered a difficult method, but it is more accurate than the previous method, and provides an accurate percentage for measuring salts, as it relies on filter papers to get rid of impurities and thus they can be measured.
The principle of operation of this method is to take a certain amount of water and pass it through a special filter paper, so that the paper gets rid of the suspended materials, dries them, weighs the sedimented materials, and thus determines the concentration of dissolved materials in the water by dividing the weight remaining on the filter paper by the amount of water that was taken before the procedure. the operation.
dissolved ions
This method is generally used to verify the validity of the results reached by the previous two methods, as it serves as evidence of the validity of the test. However, it cannot be relied upon absolutely, as it requires dozens of tests at a minimum to evaluate the percentage of salts, while it is used in general Great in designing water treatment units and devices due to their accuracy.
Conclusion
The properties of water salts are not considered a problem in themselves for some uses, as all organisms need a percentage of dissolved salts, but the percentage of these salts is what causes concern, while pure and desalinated water is the water desired by all living organisms, which requires the use of filters.
