Which of the following is likely to produce crystals if disturbed?
a supersaturated solution
Colligative properties depend on
the concentration of the solute particles
Which of the following is an electrolyte?
The tyndall effect is used to distinguish between
solutions and colloids
Effervescence is the
escape of gas from a gas-liquid solution
Raising solvent temperature causes solvent-solute collisions to become
more frequent and less energetic
Compared with a 0.01 m sugar solution, a 0.01 m KCl solution has
roughly twice the boiling-point elevation
Sugar dissolved in water is an example of which solute-solvent combination?
The solubility of substance at a given temperature is generally expressed as
amount of solute per amount of solvent
For a mixture of gases, the solubility of each gas in water varies
directly with the particle pressure of the gas
Which of the following does not increase the rate of dissolving a solid in water?
using larger pieces of solid
Henry's law relates
pressure to gas-liquid solubility
In a solution, the slightly charged part of a water molecule
attracts the ions in ionic compounds
Substances whose water solutions conduct electricity easily
ionize in water
A molar solution of CaCl2 contains
One mole of CaCl2 of every liter of solution
A substance whose water solution is a poor conductor of electricity is a(n)
What mass of water must be used to make a 1.35 m solution that contains 8.20 of NaOH?
How many moles of ions are produced by the dissociation of 1 mole of Al2(CO3)3?
The concentration of water solution of NaCl is 2.48 m, and it contains 806 g of water. How much NaCl is in the solution?
Steps on making a solution:
1) calculating the mass of solute
2) Add some solvent to the solute to dissolve, and then pour it into a 1 L volumetric flask
3) Add water until the volume of the solution nears the neck of the flask
4) Put the stopper in the beaker, and stir.
5) Carefully fill up the rest with water
6) find resulting solution and concentration
