Solubility Flashcards
What is the evidence for particles in dissolving?
Dissolving is evidence that all materials are made up of particles.
What happens to sugar when it dissolves in water?
Tiny particles break off each solid granule of sugar and mix with water particles.
What is the term for the substance that dissolves?
The substance that dissolves is called the solute.
What is the term for the liquid in which a substance dissolves?
The liquid in which a substance dissolves is called the solvent.
What do we call the mixture of dissolved sugar and water?
The mixture of dissolved sugar and water is called a solution.
What indicates a saturated solution in an experiment?
A saturated solution is indicated when there is some undissolved salt left in the bottom of the beaker.
How do you determine the solubility of salt in water?
The solubility of salt is determined by the grams of salt added per 100g of water.
What is the relationship represented by a straight line graph?
A straight line graph represents a linear relationship between two variables, expressed as y = mx + c.
What is solubility?
Solubility is the maximum mass of a solute that can dissolve in a solvent at a specific temperature. The solubility of a substance is how easily it dissolves in a liquid. It generally increases with temperature.
What happens when no more solute can dissolve in a solution?
The solution is said to be saturated.
How is solubility typically measured?
Solubility is measured in grams of solute per 100 grams of solvent.
How does temperature affect solubility?
Increasing the solvent’s temperature usually increases the mass of solute that can dissolve.
What is a solubility curve?
A graph that shows the solubility of or relationship between different substances against temperature.
What type of relationship do some solubility graphs show?
Not all graphs of solubility against temperature are linear; some are curves.
How can you find the mass of sodium nitrate needed for a saturated solution at 80°C?
Locate 80°C on the x-axis, find the sodium nitrate curve, and read the mass from the y-axis.
Draw a concentrated solution compared to a dilute solution
N/a
What is dilution?
Dilution is the process by which a concentrated solution becomes less concentrated (more dilute).
What is a saturated solution?
An unsaturated solution is when the dissolved solute is below saturated point; more can dissolve.
A saturated solution is when the dissolved solute is at saturation point;
no more can dissolve.
A supersaturated solution is when the dissolved solute is above saturated point; additional solute gathers at the bottom.
