These are two components of a solution.
What is a solute and solvent?
100
The definition/equation of molarity.
What is moles of solute/L of solution?
100

Besides stirring and heating, this is another method of increasing the rate of dissolving.

What is crushing the solute (increasing surface area)?

100
Solubility is defined as the amount of solute that is dissolved in this volume of solvent (water).
What is 100 mL?
100
Typically, compounds from the top half of the solubility chart are this whereas compounds from the bottom half of the solubility chart are this.
What is soluble in water (top half); what is insoluble in water (bottom half)
200
The substance that there is generally more of in a solution.
What is the solvent?
200
The molar concentration formed from 4.5 moles of NaCl dissolved in 1.5 L of water.
What is 3 M?
200

In order for dissolving to occur what two things need to come in contact with each other?

solute and solvent

200
Gases dissolve better at these temperatures and solids dissolve better at these temperatures.
What are colder temperatures for gases and warmer temperatures for solids?
200

"Like dissolves like" is a very general rule used for predicting whether

a solute will dissolve in the same solvent (polar - polar) (np - np)


300
This is the adjective that describes NaCl dissolving in water.
What is soluble?
300
The molar concentration formed from 25 g of NaCl dissolved in 450 mL of water.
What is 0.96 M?
300

How does increasing surface area increase dissolving rate?

More surface area - more spots for solute to interact with solvent!

300
The type of solution in which the maximum amount of solute has dissolved (and no more solute can dissolve).
What is a saturated solution?
300

  1. What volume of aqueous 3.00 M MgSO4 solution must be diluted with water to prepare 300.0 mL of aqueous 0.400 M MgSO4?

40 mL

400
Oil is said to be this in water.
What is insoluble?
400
The amount of L necessary to make a 2 M solution with 0.6 moles of sodium chloride.
What is 0.3 L?
400

How does Increasing Temperature increase the rate of dissolving?

Average kinetic energy is moving faster so more solute - solvent interactions

400
The type of solution in which no more solute will dissolve and there is some solute sitting in the bottom of the beaker.
What is a supersaturated solution?
400

What is the original stock solution molarity if it took 50.0 mL of stock solution to make 375 mL of 0.850 M solution?

6.4 M

500

Would Iodine gas (I2) dissolve in water or CCl4. Explain

CCl4 -nonpolar solvent for I2 which is a nonpolar solute

500

The amount of grams of CaCl2 necessary to make 100 mL of a 0.2 M solution

What is 2.22 grams of CaCl2?

500

How does agitation increase the rate of dissolving?

Moving particles around each other increasing solute - solvent interactions

500
If the solubility of a compound is below the line for it at a given temperature (and more solute can still be dissolved), this solution is said to be this.
What is an unsaturated solution?
500

Why do crystals not form immediately after a supersaturated solution is cooled down like our Rock Candy Simulation?

The particles of sugar need to slow down enough and then interact with the string in order to come out of solution and form the sugar crystal
