What does a solute do in a solution?
The solute is the substance that dissolves.
What type of material do you need for filtration to work?
Porous material
What common compound is considered a universal solvent?
water, H2O
Is there more solute or solvent in a solution and how do you know?
Solvent because it dissolves the solute.
True or False: Elements and compounds have the same properties.
False
What does a solvent do in a solution?
The substance that a solute dissolves into.
What strategy was used separate gold during the gold rush and why did it work?
Panning/Flotation, the density gold is different from the other rocks in the water, allowing it to be separated.
What type of mixture are all solutions?
Homogeneuos
What are our two types of mixtures?
Homogeneous and Heterogeneous
Blood is what type of mixture and why?
Heterogenous because when you look at it under a microscope you can see all the individual part of blood.
In Salt Water what is the solute, solvent, and solution?
Solute: Salt
Solvent: Water
Solution: Saltwater
What strategy did we use to separate colors in markers?
Chromatography
Accurately draw a water molecule.
Teacher will check for accuracy.
What are two examples of homogeneous mixtures?
salt water, coffee, steel, lemonade, etc.
What are two example of heterogeneous mixtures?
Gravel, trail mix, ocean water, salad, etc.
Which of the following is a solution and how do you know?
A) Mud in water
B) Sand in water
C) Sugar in water
D) Oil in water
C) Sugar in water because the sugar dissolves
Why can you use evaporation to separate different mixtures?
Different elements and compounds have different evaporation temperatures, allowing you to heat a substance up and only evaporate one part of the mixture.
It is an element, molecule, or compound?
A) H20
B) Na
C) O2
A) Compound
B) Element
C) Molecule
What is the key feature of a molecule?
- Draw and label an example of a molecule.
Chemical Bond
Draw and label an example of a compound.
H20, CO2, NaCl...
If you keep adding more solute into a solution there is a point where it will stop dissolving, i.e. salt into saltwater. What is this point called?
Saturation Point
Explain the process of distillation.
A separation of a mixture where the components of a liquid mixture are vaporized and then condensed and isolated.
Draw and label ocean water at the molecular level.
Teacher will check for accuracy.
