Растворимость веществ.

is solubility?
4. What are the 3 groups of substances divided by solubility?
5. Give examples of soluble substances.
6. Give examples of insoluble substances.
7. Give examples of slightly soluble substances.

dioxide in water. Carbon dioxide is dissolved in a drink under high pressure. When we open the bottle, the pressure decreases. The solubility of the gas decreases and it begins to flow out. We see gas bubbles.
 If you open a warm fizzy drink, then we risk pouring. Because the solubility of gases decreases with increasing temperature.
 

true or false?

1. Water is а universal solvent.
2. All solids dissolve well in water.
3. Salt and sugar are soluble substances.
4. Solubility of substances depends on temperature.
5. Solids dissolve better in hot water than in cold water.
6. Hot water contains more oxygen than cold water.
7. The solubility of gases does not depend on temperature.
8. Gases are more soluble in water at high pressure.

of solids depends on the nature of the substances and on the temperature.
3. As the temperature rises the solubility of most solids increases.
4. The solubility of gases depends on temperature and pressure.
5. The higher the temperature, the lower the solubility of gases.
6. The higher the pressure, the better the solubility of the gases.
