Anonymous users2024-02-15Affects gas solubility.
The factors are mainly pressure and temperature.
The higher the temperature, the less solubility of the gas, when we boil water, after heating, many small bubbles will be produced in the water, at this time, with the increase of temperature, the solubility of the gas in the water decreases. The higher the pressure, the greater the solubility of the gas, we open the coke or beer bottle, the pressure decreases, and the carbon dioxide is dissolved.
Foam will form and splash out, which is the effect of pressure on the solubility of the gas.

Anonymous users2024-02-14It can be explained in two ways, internal and external.
Internal factors mainly include the gas itself, for example, ammonia.
One volume of water can dissolve 700 volumes of ammonia and carbon dioxide.
It's about 1:40. In addition, whether the gas reacts with the solution or not is also related to the solubility of the gas.
External factors mainly include external temperature and air pressure. The higher the temperature, the worse the solubility of the gas. In addition, the pressure also affects the solubility of the gas.

Anonymous users2024-02-10Temperature is related to pressure. Since the solubility of a gas decreases with the increase of temperature and increases with the increase of pressure, the factors that affect the solubility of the gas include temperature and pressure.
Whether a substance is dissolved or not, and the size of its solubility depends on the nature of the substance (referring to solvents and solutes) on the one hand; On the other hand, it is also related to external conditions such as temperature, pressure, solvent type, etc. Under the same conditions, some substances are easily soluble and others are difficult to dissolve, i.e., different substances have different solubility in the same solvent.
Definition and influencing factors of gas solubility1. Definition of gas solubility: gas solubility refers to the volume of gas when the gas is dissolved in 1 volume of water at a certain temperature with a pressure of 101kpa.
2. Factors influencing gas solubility.
1) The nature of the gas.
2) Temperature: The higher the temperature, the lower the solubility of the gas.
2) Pressure: The greater the pressure, the greater the solubility of the gas.

Anonymous users2024-02-09The solubility of a gas is first determined by the properties of the gas, and also varies with the pressure of the gas and the temperature of the solvent.
When the pressure is constant, the solubility of the gas decreases as the temperature increases. This is no exception for gases, because when the temperature rises, the gas molecules move at an accelerated rate and tend to escape from the water's surface.
When the temperature is constant, the solubility of the gas increases with the increase of the pressure of the gas. This is because when the pressure increases, the concentration of the gas on the liquid surface increases, therefore, more gas molecules enter the liquid surface than those that escape from the liquid surface, resulting in a greater solubility of the gas.

Anonymous users2024-02-08Gas solubility is affected by factors such as gas type, filial piety and vertical pressure, temperature, etc
1. When the pressure is constant, the solubility of the gas decreases with the increase of temperature. Because when the temperature rises, the movement rate of gas molecules accelerates, and it is easy to escape from the water surface;
2. When the pressure is constant, the solubility of the gas decreases with the increase of temperature. This is no exception for gases, because when the temperature rises, the gas molecules move at an accelerated rate and tend to escape from the water's surface.
3. The solubility of gas fiber burial depends on the nature of the gas, and also changes with the pressure of the gas and the temperature of the solvent. The volume of dissolved gas in one liter of water is: ammonia is 702l, hydrogen is 0.01819l, and oxygen is 0.03102l.
Ammonia is easily soluble in water because ammonia is a polar molecule, and water is also a polar molecule, and ammonia molecules and water molecules can also form hydrogen bonds, and significant hydration occurs, so its solubility is very large; Hydrogen and nitrogen are non-polar molecules, so their solubility in water is very small.

Anonymous users2024-02-07Definition of gas solubility: gas solubility is the volume of gas in water when the gas disturbance pressure is 0 at 101kpa, at a certain temperature, dissolved in 1 saturation.
Factors influencing gas solubility (1) Gas properties. (2) Temperature: The higher the temperature, the smaller the solubility of the gas. (3) Pressure: The higher the pressure, the higher the solubility of the gas.
Gas solubility example.
When you open the lid of the soda, a lot of bubbles will come out of the solution, and the solubility of the gas will become smaller.
A The temperature rises, B The temperature decreases, C The pressure decreases, and the D Yuankai pressure increases.
C Analysis: After opening the soda cap, the pressure in the bottle decreases, and the solubility of the gas becomes smaller, so the answer is C.

Anonymous users2024-02-06Since the solubility of gas decreases with the increase of temperature and increases with the increase of pressure, the factors affecting the solubility of gas include the temperature and pressure
So the answer is: temperature and pressure are old; The solubility of the gas decreases with the increase of temperature and increases with the increase of pressure

Whether to write the precipitation symbol or not has nothing to do with the solubility of the substance, if there is a precipitation, write the precipitation symbol, the magnesium carbonate is generated because it forms a precipitate in the solution, even if the soluble substance is saturated and precipitated, it is also necessary to write the precipitation symbol, for example, in the ammonia industry, the soluble sodium bicarbonate has a reaction formula and the precipitation symbol is also written. And if calcium oxide forms a precipitate with water, it is also to be written. As for your exam requirements, you don't need to know so much, you only need to remember a few to write or not to write, the reactants in the equation do not write the precipitation symbol, the product in junior high school to write the precipitation symbol in addition to calcium hydroxide in the solubility table, so calcium sulfate, silver sulfate should also be written, there will be no equation I said not to write the precipitation symbol in the high school entrance examination, but it will not be in high school in the future, and calcium hydroxide, you only need to remember the reaction of calcium oxide and water to produce slightly soluble calcium hydroxide without writing, Others depend on the situation, if the title says that calcium hydroxide precipitation is generated, you need to write, if you don't say it, you don't need to write. >>>More
