SOLUTIONS?
The substance in which the solute dissolves
What is the solvent?
True or False: heating always increases the rate of solubility of all substances.
False
a substance with a lot of solute is said to be
Concentrated
whipped cream
Colloid
What percent concentration is a solution that has 10 g of solute and 200 mL of solvent?
5%
A mixture that appears to be a single substance, where particles of 2 or more substances are distributed evenly throughout each other.
Solution
Decreasing the temperature
A solution that contains very little solute is considered to be
Diluted
corn starch and water
Suspension
if I have a 50 mL solution with a concentration of 4% what amount of solute is in the solution?
2g
A mixture in which the particles are evenly dispersed, but are not heavy enough to settle out.
Colloid
How does pressure affect the solubility of a gas?
If pressure increases over a liquid then the solubility of gas will increase.
What does PPM mean?
parts per million
sand and beans
mixture
