3.6 - Molar Concentration Flashcards
What do you call a solution where the solvent is water?
Aqueous solution.
Define the solute and solvent of a solution?
Solute dissolves into solvent.
What do you call the ratio that describes the amount of a mixture’s component to the total volume of the mixture? (part to whole)
Concentration.
What two adjectives can we use to describe concentration of a solution in a qualitative way?
Dilute and concentrated.
What word describes a solution with low concentration?
Dilute.
What word describes a solution with high concentration?
Concentrated.
What is another word for molar concentration?
Molarity.
What the you call the concentration of a given solute in solution, expressing # of moles in 1 L of solution?
Molar Concentration/Molarity.
What are the units of molarity/mole concentration?
mol/L but mostly M (pronounced molar)
How do you represent that you are showing the molarity of a chemical formula?
Square brackets around that formula.
On the mole conversion diagram, the branch relating to molarity gets you what?
Volume (solutions).
What do you call a solution whose concentration you know relatively precisely?
Standard solution.
What is one technique for determining the unknown concentration of a solution?
comparing to a solution whose concentration you do know (standard solution).
The conversion factor of molarity is what?
moles of solute/Litres of solution or Litres of solution/moles of solute.
When ionic compounds dissolve in water, what happens to them?
Their charged pieces separate (dissociate and no longer attract each other)
What do you call the separation of the component ions of an ionic compound when it dissolves in water?
Dissociation
How do you represent the dissociation process with formulas?
An equation (resembles a decomposition equation).
When dissociation occurs, does the volume of the solution change?
No (only meaningful conversion factor at this point would be mole ratio).
