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)
