A solution is made by adding 200 g table salt to 1 L water. The solubility of salt is
36 g/100 mL water.
Which term best describes this solution? - ANS - Unsaturated
\A spoon of salt is added to water. Which of these will increase how fast the salt
dissolves? - ANS - Stirring the salt and water.
Crushing the salt so the grains are smaller
\Analyze the graph to describe the solubility of barium nitrate, BaNO3.
At O degrees the solubility is at 50.
At 20 degrees it is at 99.
At 40 degrees it is at 148.
At 60 it is at 200.
At 80 it is at 275.
At 100 it is at 349. - ANS - At 60°C, 200 g must be added to 1 L of water to make a
saturated solution.
At 25°C, the solubility is about 100 g per liter
A solution that contains 600 g BaNO3 in 3 L of H2O at 70°C is
unsaturated.
For a solution that contains 300 g BaNO3 in 3 L of H2O at 60°C to become
saturated, 300 g g solute must be added
\Does oil and water form a solution? - ANS - No, because oil is non-polar and
water is polar.

\How do different factors affect solubility? - ANS - Increasing the temperature
decreases the solubility of gases.
Decreasing temperature decreases the solubility of solids.
Increasing pressure increases the solubility of gases.
\Increasing pressure - ANS - increases the solubility of gases
has little affect on the solubility of solids and liquids.
\Increasing the temperature - ANS - increases the solubility of solids and liquids.

\Pellets of calcium chloride are spread on a sidewalk covered in water that is
36°C. Under which circumstance will the calcium chloride dissolve faster? - ANS -
People walking on the sidewalk crushthe calcium chloride pellets.
\Rate of dissolution - ANS - Describes the rate or speed at which solid dissolves
in a liquid.
It is affected by:
- Stirring
- Surface area
- Temperature
