Which of the following is an example of Heterogeneous Mixture?

A. Coffee
B. Oil and Water
C. Salt Water
D. Mouth Wash

I think it is C am I right?

nope: saltwater is a solution, homogenous

thank you

well is it B then that was my next choice

Yes, you're correct! Saltwater is an example of a heterogeneous mixture. Now, let me explain how we arrived at this answer.

To determine whether a substance is a homogeneous or heterogeneous mixture, we need to understand the definitions of both terms.

A homogeneous mixture is one that has the same composition and properties throughout. In other words, the components are uniformly distributed and not visibly distinguishable from one another.

On the other hand, a heterogeneous mixture is one in which the components are not evenly mixed, and you can see the different substances within the mixture.

Now, let's consider the options provided:

A. Coffee: Coffee is typically a homogeneous mixture, as the coffee particles dissolve evenly in the water. It does not exhibit different regions or visible separations, so it is not an example of a heterogeneous mixture.

B. Oil and Water: This mixture is a classic example of a heterogeneous mixture. Oil and water do not mix well, and they separate into different layers when left undisturbed. You can visibly see the distinct oil and water layers, making it heterogeneous.

C. Saltwater: Saltwater is also an example of a heterogeneous mixture. Although it may seem surprising, it is not a homogeneous mixture because the dissolved salt particles are not evenly distributed throughout the water. If you were to observe saltwater under a microscope, you would find small salt crystals dissolved unevenly in the water.

D. Mouthwash: Mouthwash is typically a homogeneous mixture because all its components, including active ingredients and flavoring, are mixed uniformly. There are no visible regions or separations, making it a homogeneous mixture.

So, in this case, the correct answer is indeed option C, Saltwater. Good job!
