solutions exam
a metal solution is a(n) - ANS - alloy
\a molar solution of CaCl2 contains - ANS - one mole of CaCl2 for every liter of
solution
\a solute crystal is dropped into a solution containing dissolved solute, it falls to
the bottom of the beaker and does not dissolve after vigorous stirring. What does
this indicate about the solution - ANS - it is probably saturated
\a substance whose water solution is a good conductor of electricity is a(n) - ANS
- electrolyte
\a substance whose water solution is a poor conductor of electricity is a(n) - ANS
- nonelectrolyte
\all of the following are homogenous mixtures except - ANS - soil
\an apparatus for testing conductivity is placed in a solution. The power supply is
turned on and the light bulb glows brightly. This indicates the soltuion - ANS -
contains an electrolyte
\an endothermic dissolution process - ANS - absorbs energy as heat and has
positive enthalpy of solution
\an NaOH solution contains 1.90 mol of NaOH, and its concentration is 0.555 M.
What is its volume - ANS - 3.42 L
\as temperature increases, solubility of gases in liquids - ANS - decreases
\as temperature increases, solubility of solids in liquids - ANS - usually increases
\carbon dioxide dissolved in water is an example of which solute-solvent
combination - ANS - gas-liquid
\during the dissolving process, which particles interact - ANS - solute and solvent
\for a mixture of gases, the solubility of each gas in water varies - ANS - directly
with the partial pressure of the gas
\how many milliliters of a 0.171 M solution contains 1.00 g of NaCl - ANS - 100 mL
\How many moles HCl are present in 0.70 L of a 0.33 M HCl solution - ANS - 0.23
mol
\if a solution is not agitated while it is being made, dissolved solute tends to -
ANS - build up in the solvent near the solute
\if the amount of solute present in a solution at a given temperature is less than
the maximum amount that can dissolve at that temperature, the solution is said to
be - ANS - unsaturated
\in a solution at equilibrium - ANS - the rate of dissolution is greater than the rate
of crystallization
