Would I be able to separate everything back out again? > !!! Why or why not? How about just the flour or the sugar? --- ## Heterogeneous Mixtures A bag of jellybeans is a mixture that I can separate out. !!! (If you're like me you can pick out the popcorn ones and throw them away!) ![jellybeans](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse1.mm.bing.net%2Fth%3Fid%3DOIP.dALm2XOZRVDNwV4duEAg2QHaE7%26pid%3DApi&f=1 style="height: 5rem") --- !!! tip: Heterogeneous Mixtures * Heterogeneous (Hetero-: different -geneous: kind) * Mixtures that have components that are not uniform or have regions with different properties are called **heterogeneous mixtures**. * You can pick out the different parts out (or at least see the different parts) ![fruit salad](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Farts2science.files.wordpress.com%2F2015%2F05%2Ffruitsalad1_460.jpg%3Fw%3D460%26h%3D460&f=1&nofb=1 style="height: 5rem") ![trail mix](https://external-content.duckduckgo.com/iu/?u=http%3A%2F%2Fcontextuallc.com%2Fwp-content%2Fuploads%2F2018%2F03%2Fmixture.jpg&f=1&nofb=1 style="height: 5rem") --- ## Homogeneous Mixtures Sometimes mixtures don't look like mixtures at all. ![orange juice](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fwww.tasteofhome.com%2Fwp-content%2Fuploads%2F2018%2F05%2Fshutterstock_390619453.jpg&f=1&nofb=1 style="height: 5rem") ![sodas and teas](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fwww.fodors.com%2Fwp-content%2Fuploads%2F2019%2F03%2FHERO_Worlds_Best_Soda_Bundaberg_shutterstock_679079920.jpg&f=1&nofb=1 style="height: 5rem") --- ## Solutions When we added sugar to water, we couldn't see the sugar because it dissolved. !!! tip: Solutions You may already know that when we mix something together into a liquid it is called a **solution**. ![solute and solvent make a solution](https://external-content.duckduckgo.com/iu/?u=http%3A%2F%2Fdr-illustration.co.uk%2Fwp-content%2Fuploads%2F2013%2F02%2FSolute-and-solvent1.png&f=1&nofb=1 style="height: 5rem") --- ## Classifying Solutions !!! tip: Dilute Solution When a small smount of solute is dissolved in the solvent it becomes a **dilute solution**. !!! tip: Concentrated Solution When a large amount of solute is dissolved in the solvent it becomes a **concentrated solution**. ![](https://external-content.duckduckgo.com/iu/?u=http%3A%2F%2F2.bp.blogspot.com%2F_gJ3siYfRxWo%2FTFkwVhzUOaI%2FAAAAAAAAAB4%2FulJxCyTVtxs%2Fs320%2FC%2Band%2BD.JPG&f=1&nofb=1 style="height: 5rem") --- ## Saturated Solutions In our lab, we added sugar until no more would dissolve. When solutions reach this point, they are called **saturated solutions**. If we were to continue to heat up our water, we could add more sugar. The solution then is called a **supersaturated solution**. ![](https://external-content.duckduckgo.com/iu/?u=http%3A%2F%2Fstudy.com%2Fcimages%2Fvideopreview%2Fsaturated-solution-definition-examples-quiz_01024911_117169.jpg&f=1&nofb=1 style="height: 5rem") ![](https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fchem.libretexts.org%2F%40api%2Fdeki%2Ffiles%2F42974%2F45b1d9d593a104eefb5baeeddb11e407.jpg%3Frevision%3D1&f=1&nofb=1 style="height: 5rem")
