Ph aquarium water. Hardness and pH of drinking water: why water

Water from a be-yak dzherel, like a lake, like a river, like a natural broth, for some nameless elements (variety of salts, minerals, gases) From the lessons of chemistry, it is clear that the speech is not arranged near the water in a clean look. For example, if water mixes the same kitchen force - sodium chloride (NaCl), then it will dissociate into ions: Na + cation and Cl- anion.

Dissociation to sodium chloride (NaCl)

In a similar rank, it comes from more speeches, the very quantity of these positively and negatively charged particles signify the hydrochemical warehouse of water, which without intermediary influx into the self-feeling of your aquarium vikhovants.

It is important for an aquarist to know at least two important mutually important water parameters: hardness and water indicator (pH indicator). The stench obov'yazkovo vkazayutsya in the minds of the Utrimannya of that chi іnshoy type of rib.

Water hardness

The hardness of water depends on the number of differences in mineral salts of calcium (Ca+ cations) and magnesium (Mg+ cations). For example, they are richly divided, which means the water is thick, for example, there is little softness. It has historically developed that in Russia hardness means German degrees dGH. In other countries, vicorist has its own definition, for example, American degrees (usH), the unit of hardness is ppm (part per million - one part per million). Most of the sales we sell in ppm electronic virіrnikіv water hardness.

For equal hardness, the water is appointed by the offensive rank:

• vіd 0 to 4 dGH - narrower than soft,
• vіd 5 to 10 dGH - soft,
• vіd 10 to 20 dGH - medium hardness,
• vіd 20 to 30 dGH – zhorstka
• over 30 dGH - just a little bit.

Optimum range of more species of ribs is between 0.2 and 20 degrees dGH.

Not varto rogue Zhorstkіst z Mineralizatsiєyu, in the rest of the fall at the waters of the river, there were added impersonal salts, which in some cases should not be avenged by calcium and magnesium. So, having repaired all the same kitchen power by the water, we will have more mineralization, but at the same time, we will get rich on a colossal equal.

You see the post-time that timchasov (carbonate) hardness, the rest you can see just boiling, that and timchasov. The addition of both gives the hot hardness of dGH.

timchasova + post_yna \u003d fierce hardness

The constant hardness is caused by the differences in chlorides, sulfates and other salts, as a result, the water is saturated with Mg+ and Ca+ ions and their partners SO4 and Cl. In the booty postiyna zhorstkost I don’t show myself in any way on the vіdmіna vіd timchasova.

Constant hardness of the water

Timchasovy zhorstkіst krіm known ionіv (Mg+, Ca+, SO4-, Cl-) may add hydrocarbonate anion - HCO3, yakі when heated fall into the siege, vіdomiy yak scum, which is deposited on the walls of teapots and other utensils during boiling.

Water indicator (pH indicator)

Water indicator, or pH indicator, indicates the number of free ions in water (H +), or rather, the ratio of H + and OH- (at the same time, give the known formula H2O). Water by itself practically does not dissociate into H + and OH-, but shards in it are present large number house, deyakі z them give khіmіchnu reaction, zmіschuyuchi vodnevny pokaznik in that chi іnshiy bіk. Even though there is a lot of ion in the water, the water is rich, the water is sour, and there is little puddle.

Ionic acidic pH storage

The ionic warehouse of the puddle pH value

The pH indicator changes from 0 (the water is too acidic) to 14 (the water is too puddle). On the vіdmіnu vіd zhorstkostі vody, znachennya water showcase the same in all lands, that swindler does not seem to. Ribis can live at 5 to 9 pH. The middle of the scale under number 7 (pH7) means neutral water - the best for more species of aquarium fish and roslin.

Water is added like this:

• pH<5 - сильно кислая,
• pH 5-6 - acidic,
• pH 6-6.8 slightly acidic,
• pH 6.8-7.2 - neutral,
• pH 7.2-8.0 slightly puddle,
• pH 8.0-9.0 - puddle,
• pH>9 - a puddle.

In an aquarium, the pH indicator is no longer stable, especially in soft water, and can change with the passage of the day in that hour, it sounds in the range of 6.5-8.5. The most invested in new carbon dioxide, which vibrates with ribs and roslins (at the night time), those different organic inputs (excrement, not from the surplus of їzhі), yak take an active part in the oxidized water.

Іsnuє vzaєmozv'yazok mizh zhorstkіstyu water and equal pH. Zhorstka water, full of mineral cavities, as a rule, puddle, and m'yaka water- sour. Mineral dispersal acts like a buffer, resists oxidation, so in solid water the pH value changes and does not fall below 7.0

The power of the water element is practically boundless. Vaughn can bestow life and with such success itself take away її. In order to raise water to your supremacy ally in the plan to improve that health, people need to know the quality of water, and in times of consumption - to change the power of that chi other bek. Who knows a lot about such understanding, like zhorstkіst drinking water and the pH of the drinking water, but often they get confused. If you talk about butylovane, then there is not much turbulence about it. And the axis of the valley with running water is more important to know the difference between the density and pH of the drinking water, so let's sort it out.

Two sides of the same coin, what are the same dimensions?

The people have an idea that the severity of drinking water and pH can be considered as synonyms, the opposite of two different speeches. The concept of "zhorstkіst" zastosovuєtsya all the way to water, and zhorstkіst water to deposit in the amount of magnesium, calcium and other varieties of salts of meadow earth metals. In my own room, pH is a universal indicator of acid-luzhnoy rіvnovagi, whether it be water, shelter, beer, tomato juice, or even a motherland. The pH value of 0 is pure acid, and pH 14 is pure meadow.

Why is it important to know the hardness of drinking water?

It is clear from the fact that the concentration of salts is increased to make the water hard, and lowered, on the contrary - soft. At the most important level, the water from the tap is too hard, so fakhіvtsі recommend installing a helper, tobto. pobutovy, like crushing running water with m'yakshoy. For the help of the day of helping the process of calming the zhorstkoy drive, you can mother in the region of bad luck, which you need to finish for an hour. Below, we pererahuemo only nayimovіrnіshi problems:

• z'yavlyaєtsya scum, which is a nuisance to plumbing, we will use accessories and radiators of the scorching system;
• more vitraty of miyuchikh zasobіv, and after accepting the soul, you can blame the teasing shkіri;
• in the drifts, salt is deposited, in the teeth, in the teeth, in the nirks, the liver can become a stone.

Why does the varto determine the pH of drinking water?

In order to tell about the role of water in the human body, even drinking water is poured into all the processes of life. If the pH level is normal (approximately 7-7.5), then the person will feel good, and if the pH level is low, dryness in the mouth, headache, anxiety, sleeplessness, decreased arterial pressure and so on. Fortunately, at the same time, it’s easy to find special ones at the sale, how to make running water more adventitious for drinking and preparing it.

Looking back at all the above, you can have a pleasant taste in someone who has a hardness of drinking water and pH of drinking water. є however, as important indicators of the quality. Ale persh nizh robiti be-yak_ kroki, radimo and d_znatisya about її khіmіchny warehouse.
