Science Mixtures & Solutions Definitions

The process that changes liquid into gas, leaving any dissolved solid material behind.
A characterization of an object; something you can observe such as size, color, etc.
A substance that dissolves into a solvent, forming a solution.
A special mixture formed when a material dissolves into water. Solution is created when mixing a solid and liquid together and the solid disappears or dissolves.
Two or more material stirred together.
The process in which one material dispenses uniformly into another material
A property of an object that describes its appearance.
A property of an object that describes how it feels
Typically found in square shaped marked with an X from corner to corner.
A substance that dissolves a solute to form a solution.
A solid form of material that can be identified by its properties, such as shape, color, and pattern.
A natural susbtance found on earth.
The tiniest piece of an element.
Two or more elements chemically combined together.
A piece of solid material
Give examples of mixture.
1. A handful of sand is a mixture of several different things

2. Vegetable Soup is a mixture because it has more than 2 ingredients in it

Remember a mixtyure is formed when 2 or more different materials/objects are put (mixed) together.
Give examples of solution
Solutions are always clear and can be seen through. An example of a solution is ice tea or lemondae
Tell when a solution is formed?
When the solute (example: solid ice tea mix) dissappears in a liquid. The solvent (example: water) is what dissolves the solid (solute)
What is the difference between a mixture and a solution?
a mixture is when you mix two or more things together and a solution is when you make a solution and you mix two things together, one of the things dissolves into the other.
Explain the process for separating mixtures and solutions?
Mixtures you separate by filtering and solutions through evaporation
Explain the process of separating gravel & water?
You pour the mixture through a screen filter and the the gravel and water separate.
Explain the process of separating powder & water?
You use a paper filter and you pour the water and powder through the screen the water goes through and the powder will stay on top of the paper filter.
Explain the process of separating saltwater solution?
The solution, saltwater, can be taken apart through the process of evaporation.
Salt is made up of what 2 elements?
Salt is made up of sodium (Na) and chlorine (Cl).
How are salt crystals identified?
They form an x in the corner of the dish.
Explain the difference between a mixture/solution and a compound
A mixture is formed when 2 or more different material/objects are put together.

A solution is created when mixing a solid and liquid together and a the solid disappears or dissolves.

A compound is 2 or more elements chemically combined together.
1 mL of water equals
1 gram
Salt is also known as
Who was Humphrey Davy
He was an English scientist who found a way to separate the two elements that make up salt.
Which element according to the period table is the lightest,Hyrogen or Helium?
How are screen filters and paper filters different?
They separate different size particles.
Describe how you can identify the mass of salt in a saltwater solution?
You would actually have to allow the water to evaporate and once the water has evaporated you would find the salt stayed in the cup.
When a liquid evaporates and changes what does it change into?
After the liquid has evaporated and changes into gas what does it rejoin?
The water cycle
What can mixtures be separated through?
How can solutions only be separated?
Through evaporation
Give examples of elements
Give examples of solutions
saltwater, ice tea, Sprite
Give examples of mixtures
chicken soup, salad, bag of coins, chocolate milk, gravel & water, handful of sand
Give examples of compounds
air, salt
Describe when you created a separtate 2 mixtures
I took 5 ml of salt and stirred with 50 ml water
The salt dissolved into the water and made a solution. I was able to separate it through evaporation. The water turned to a gas leaving behind the salt in a crystalized form.
