Homogenous and Heterogenous Mixture

MIXTURE

• is a material made up of two or more different substances which are physically combined.

• the physical combination of two or more substances in which the identities are retained and are mixed.

TWO TYPES OF MIXTURES

Homogeneous & Heterogeneous

• Looks like one substance
• One phase
• Two or more substances
• “NaCl and H2O”

• Anything dissolved in H2O
• Salt Water
• Air (“O2 and N2 and CO2”)

Examples:

How to Distinguish

Homogeneous mixture

• the components of the mixture are uniformly and evenly mixed throughout

• sample taken with the same mixture have the same composition

​

• Can see separation of

different substances

• Two or more phases

• Oil and Vinegar
• Granite
• Potting Soil

Examples:

How to Distinguish

Heterogeneous mixtures

• the components of the mixture are not uniformly mixed throughout sample taken with the sample mixture have different composition

​Key Takeaways

1. The key difference between homogeneous and heterogeneous mixtures lies in the uniformity and visibility of their components.

2. Homogeneous mixtures have uniform composition throughout, with only one phase of matter, such as air and sugar water.

3. Heterogeneous mixtures contain distinct regions with different properties and multiple phases, like cereal in milk and vegetable soup.
