This is our assignment for mixtures: we have to write a blog post that has written descriptions, examples, and pictures of solutions (homogeneous mixtures), mechanical mixtures (heterogeneous mixtures), unsaturated solutions, and saturated solutions.
Homgeneous Mixtures (Solutions)
What is a homogeneous mixure, or a “solution?” In a homogeneous mixture, the particles of the pure substances mix together so completely that the mixture looks and feels like it is only one substance; the properties are always the same. Examples of solutions are: drink mixtures, water, air, milk, and paint. Here are some images of homogeneous mixtures:
< I made this one myself on Paint. It shows the process of pouring iced tea crystals into water, and how they mix to what appears to be one substance. This is a homogeneous mixture.
< This one is from Google.ca/images. See how when you pour in the Kool-Aid it looks as if the drink crystals and water are all just one substance? This is called a solution.
< This one came from Google Images as well. The paint appears to be all one substance and colour, but there are a lot of different chemicals that make up paint.
Heterogeneous Mixtures (Mechanical Mixtures)
A heterogeneous mixture, also known as a “mechanical mixture,” is a mixture where two or more substances can be seen and felt; the substances may have different properties compared to a different sample. Examples of mechanical mixtures are: granola bars, bird seed, limestone, cement, asphalt, and trail mix. Here are some pictures of heterogeneous mixtures:
< Again, I made this one myself on Paint. It shows three different examples of mechanical mixtures, and why they are considered to be mechanical mixtures.
< This is from Google Images. It’s a picture of asphalt up close. You can see all of the different rocks that make it up.
< Again, got it from Google.ca/images. You can see the assortment of nuts making up the trail mix, with an occasional berry here and there.
Unsaturated Solutions
An unsaturated solution is a solution that still contains unfilled spaces between the particles. For example, have you ever made a drink using drink crystals, like iced tea or Kool-Aid? Has it ever tasted too watery? That’s because there aren’t enough drink particles to fill up the spaces of the water particles. To get the non-watery taste, just add more drink crystals to the water.
< I made this picture on Paint. It shows how the iced tea particles don’t fully fill the spaces between the water ones, so the iced tea is much too watery.
< From Google Images. This iced tea could really use some more drink crystals! Doesn’t look strong enough to me.
< A picture of lemonade from Google.ca/images. It doesn’t look strong enough to me, but it doesn’t need that many more lemonade drink crystals. It does need more though.
Saturated Solutions
A saturated solution is the complete opposite of an unsaturated solution: all of the spaces are filled in it. When you make iced tea, lemonade or Kool-Aid, and it tastes just as it should, then the solution is saturated because the drink crystals fill up the spaces between the water particles.
< I made this picture on Paint. It shows the different kinds of drink particles filling up the spaces completely between the water particles. The drinks turn out exactly like they should.
< Credit to Google.ca/images for this picture. It’s a glass of saturated iced tea.
< Again, credit to Google Images for this image. This is completely saturated lemonade! It’ll taste exactly like it should and it looks like it was made correctly.
Anyways, this is the end of this blog post. Hopefully it gave you a better understanding of homogeneous mixtures (solutions), heterogeneous mixtures (mechanical mixtures), unsaturated solutions, and saturated solutions!
