Homogeneous
  • Homogeneous mixtures are a substance in which components are evenly mixed. It has to be two or more substances and the substance has to stay the same throughout.
  • Homogeneous mixtures are also called solutions and they are formed when one substance dissolves into another substance.
  • Most homogeneous mixtures can be considered solutions, but since the rule is two or more substances a 50:50 mixture is technically not a solution.
  • Some mixtures start out as heterogeneous mixtures but can be turned into a homogeneous mixture by shaking the substance.
  • A reaction between two gases, two liquids or two solids is homogeneous.
  • To make it simple, think of Gatorade, it has salt and sugar and all those different things in them but all you can see is the colored liquid.

This is a homogeneous mixture because it has minerals and lots of other substances in it is clear throughout the whole drink and isn’t different in parts of the drink.


Heterogeneous
  • A reaction between a gas and a liquid, a gas and a solid or a liquid and a solid is heterogeneous.
  • Heterogeneous can be colloids, emulsions and suspensions.
  • Things that need to be shaken are usually suspensions because they begin as a heterogeneous mixture.
  • A heterogeneous mixture is basically a mixture with a substance in which components are not evenly mixed.
  • This is a heterogeneous mixture because you can see all of the different things like the meat, the onions, the peppers and the mushrooms.
  • To be a heterogeneous mixture you have to have at least 2 or more substances. They also cannot be evenly mixed; you also have to be able to see different substances and parts.
  • pizza_heterogeneous.jpg
    This pizza is a heterogeneous mixture because you can see all of the different ingredients and the pizza does not stay the same way all throughout itself.

The Differences Between Heterogeneous and Homogeneous Mixtures
  • The difference between the two is that heterogeneous mixtures you can see the different mixture but in homogeneous you can’t.
  • The combinations with the gas, liquid and solid substances are different and so are the foods. What I mean by that is, there can’t be a food that is a homogeneous and a heterogeneous mixture.
  • We use see these mixtures every day in our lives, we just don’t take the time to figure out what kind of mixture they are.

ChaseC773_Diagram_for_Heterogeneous_and_Homogeneous_Mixtures.jpg
This diagram is about heterogeneous and homogeneous mixtures becaue it shows a pizza and you can see the different components. Then it shows Gatorade and you can't see all of the different components.



Glossary
  • Homogeneous mixtures: A substance with two or more components that are evenly mixed or the same throughout. To make it simple, you can’t see the different components or parts.
  • Heterogeneous mixtures: A substance with two or more components that aren’t evenly mixed and don’t stay the same throughout. You can see the different components and parts.
  • Components: An ingredient or a small part of a substance. Like pepperoni on pizza, it is an ingredient on pizza.
  • Substance: Food that is made up of different components or parts. Like a pizza, it has components like dough, crust, toppings, cheese and tomato sauce.
  • Solutions: Is the same as a Homogeneous mixture because it is just a gas, liquid or solid dissolving evenly into another gas, liquid or solid.
  • Emulsions: Any colloid like suspension of a liquid in another liquid.
  • Colloids:A colloid is a substance microscopically dispersed evenly throughout another substance.
  • Suspensions: the particles of a substance are mixed with a fluid but are not dissolved.
