Key Terminology
This is the state where the solvent can no longer dissolve the solute; the maximum amount is dissolved. (Hint: Think about our Tea and Sugar Lab)
What is Saturated?
Dilute and concentrated are examples of these descriptive terms (based on how the solution looks.)
What are Qualitative terms?
This factor increases solubility because you can dissolve more sugar in heated water than cold water.
What is Temperature (or Heat)?
This technique uses magnets to recover materials like iron and steel in recycling centers.
What is Magnetism?
This disposal method's negative impacts include nutrient pollution and oxygen depletion.
What is Sewage Disposal?
If you add more sugar to your tea and it dissolves completely, the solution is currently this type.
What is Unsaturated?
This component of the solution is present in the largest quantity, like the water in lemonade.
What is the Solvent?
Increasing this factor can force more gas to dissolve, as is done when making pop. (Hint: this factor is key to carbonating liquids)
What is Pressure?
Atechnique for sorting solids based on their sizes by shaking materials as they pass through a mesh or screen.
What is Sifting?
Pollution, toxicity, and oxygen depletion are all examples of this type of environmental impact.
What is a Negative impact?
A solution with a lot of dissolved solute is described using this qualitative term. (e.g., a can of frozen orange juice)
What is Concentrated?
Observations of a solution determined by measuring mass (e.g., 10g of salt) or volume.
What are Quantitative observations?
A factor (along with temperature and pressure) that affects the saturation level of a solution.
What is Polarity?
This method is suitable for separating a homogeneous liquid/solid mixture, like making maple syrup from sap. (Hint: This process involves boiling the liquid away.)
What is Evaporation?
This disposal method carries the risk of a nuclear meltdown if storage or containment fails.
What is Radioactive Waste Disposal?
This term describes a solution with a small amount of dissolved solute. (Ex. Weak Coffee)
What is Dilute?
A solution is described as this type of mixture because its substances are dissolved evenly throughout. (Hint: consists of parts all of the same kind.)
What is Homogeneous?
The point when the solvent can no longer dissolve the solute. This is the maximum amount of solute the solvent can hold
What is the saturation point?
This technique separates solids from liquids by passing the mixture through a barrier, like using a coffee filter.
What is Filtration?
A negative environmental impact of this disposal method is the leaching of heavy metals and solvents into the soil or groundwater.
What is Paint Disposal?
This unstable solution holds more solute than it normally could at a given temperature, often made using heat.
What is Supersaturated?
The concentration of rubbing alcohol being 70% is an example of concentration measured using this. (Hint: Think about the space being occupied in the container)
What is Volume?
Name all three independent factors that determine the saturation point of any solution, such as a saltwater mixture.
What are Temperature, Pressure, and Polarity?
This technique separates a mixture of liquids by vaporizing and condensing, used to create pure water from salt water.
What is Distillation?
This is one positive environmental impact of proper sewage disposal that prevents diseases. (Hint: This is a major benefit to public health)
What is Disease Prevention (or Stopping the spread of pathogens)?
