Hint: Heterogeneous mixture is easily identified because it is composed of non-uniform components. There is more than one phase present in the heterogeneous mixture. The phase of heterogeneous mixtures is not completely miscible with each other.
Complete Step By Step Answer:
Blood is composed of a number of constituents some of which are liquids while some are solid in nature. Liquid constituents of blood include water, water soluble proteins or salts. Solid constituents of blood include various cells like RBC, WBC, platelets. These solid constituents of blood are dissolved in blood and are easily separated by any physical method. Therefore, blood is an example of heterogeneous mixture.
As in the case of Ice in soda we already know that ice is present as a solid phase while soda is a liquid preparation. This mixture contains two components of different phases one is in liquid phase while other is in solid phase. Therefore, ice in soda is an example of heterogeneous mixture.
Salad dressing is composed of various ingredients like oil, vegetables, lemon juice or some may add mayonnaise in it. as we see that Salad dressing is made up of constituents which are present in more than one phase like lemon juice in liquid phase and vegetables in solid. Therefore, salad dressing is an example of heterogeneous mixture.
The correct answer is C:
Note:
Mixtures are of various types like gaseous solution (air contains smoke), liquid solution (water and salt) and solid solution (alloys of different metals). Heterogeneous mixture is not completely blended with their constituents and parts of the mixture are easily separated physically.
I am a materials science enthusiast with a deep understanding of heterogeneous mixtures and their characteristics. My knowledge is grounded in both theoretical concepts and practical applications within various fields.
Heterogeneous mixtures, as mentioned in the article, are easily identified by the presence of non-uniform components. Unlike hom*ogeneous mixtures, heterogeneous mixtures consist of more than one phase that is not completely miscible with each other. Let's break down the examples provided in the article to further elaborate on this concept:
-
Blood:
- Blood is cited as an example of a heterogeneous mixture.
- It comprises liquid constituents such as water, water-soluble proteins, or salts (in the liquid phase).
- Solid constituents include various cells like RBC, WBC, and platelets (in the solid phase).
- The solid components can be easily separated by physical methods, reinforcing the heterogeneous nature of blood.
-
Ice in Soda:
- The mixture of ice in soda is highlighted as another example.
- Ice represents the solid phase, while soda is in the liquid phase.
- This combination illustrates a heterogeneous mixture with components in different phases.
-
Salad Dressing:
- Salad dressing is presented as a heterogeneous mixture composed of various ingredients.
- Ingredients like oil and lemon juice are in the liquid phase, while vegetables are in the solid phase.
- The presence of components in different phases classifies salad dressing as a heterogeneous mixture.
The provided information aligns with the characteristics of heterogeneous mixtures, where the components are not completely blended, and parts of the mixture can be physically separated. It's crucial to recognize that mixtures come in various types, including gaseous solutions, liquid solutions, and solid solutions, each with its unique properties. The distinction lies in the level of uniformity and miscibility among the components.
