10 Questions
Potassium nitrate and sodium chloride have the same solubility at all temperatures.
False
Potassium nitrate and sodium chloride are both metals.
False
Solubility is a property of every substance.
True
Solubility is only temperature-dependent.
False
When the temperature rises, the energy of the solid particles remains the same.
False
The solvent particles move slower in all directions when the temperature rises.
False
Solubility is the ability of a solvent to dissolve in a substance.
False
The increased temperature has no effect on the solubility of a substance.
False
Solubility increases with temperature because the solvent particles are surrounding the solid particles.
True
The increased movement of particles due to the increase in temperature causes the solid particles to come together.
False
Study Notes
Solubility
- Solubility is a property of every substance, describing its ability to dissolve in a particular solvent.
- It is scientifically defined as the maximum amount of a substance that will dissolve in a certain amount of solvent at a certain temperature.
- Different substances have different solubilities.
Solubility of Salts
- Potassium nitrate and sodium chloride are both compounds known as salts.
- They exhibit very different solubilities at different temperatures, as shown in Figure 10.5.
Solubility and Temperature
- When the temperature rises, the energy of all particles (solvent and solid) increases.
- Solid particles vibrate more as temperature increases, causing them to separate and spread out.
- Solvent particles move faster in all directions, hitting the solid particles more frequently, which helps to break them apart.
- Increased movement of particles due to increased temperature enhances the solubility process.
