Question

Define the following giving one example of each:
A. Homogeneous mixture
B. Heterogeneous mixture

Answer 1

Homogeneous mixture

• These are the types of mixtures in which the components mixed are uniformly distributed throughout the mixture. In other words, “they are uniform throughout”.
• We can observe only one phase of matter in a homogeneous mixture. Key points regarding such mixtures are:
• Particles are distributed uniformly
• We can’t judge a homogeneous mixture by just seeing it
• Homogeneous mixtures are also called solutions
• Uniform composition
• Example: rainwater, vinegar, sugar water etc.
  

Heterogeneous mixture

• This is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope.
• We can easily identify the components and more than one phase can be seen by naked eyes.
• Particles are distributed non-uniformly
• We can judge a heterogeneous mixture by just seeing it
• Non-uniform composition
• Examples are: mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a salad, trail mix
