Question

Consider the following statements regarding heterogeneous mixture. Identify the correct ones.

1. A heterogeneous mixture is a mixture with a uniform composition that contains components in different phases.
2. Concrete is the example of a heterogeneous mixture, a combination of cement and water.

1. Only I 
2. Only II
3. Both I & II
4. None I & II

Answer 1

Correct Answer - Option 2 : Only II

The correct answer is Option(2) .i.e.Only II. 

• A heterogeneous mixture is a mixture with a non-uniform composition that contains components in different phases.
• Concrete is the example of a heterogeneous mixture, a combination of -cement and water. 
• Mixture-
  • A mixture is described as a result of combining two or more substances.
  • Each substance maintains its chemical identity.
  • In other words, within the components of a mixture, a chemical reaction does not occur.
• Heterogeneous mixture:
  • A heterogeneous mixture is a mixture with a non-uniform composition that contains components in different phases.
  • The non-uniform composition with at least two phases varies from one region to another 
  • It remains separate from each other, with clearly identifiable properties.
  • This type of mixtures contain particles that sustain their chemical properties when they are mixed.
  • It can be distinguished after they are mixed.
  • Through the filtration of chemical procedures, the components of heterogeneous mixtures can be separated.
  • The two types of heterogeneous mixtures are colloids & suspensions. 
• Example:
  • Concrete is a heterogeneous mixture of an aggregate: water & cement
  • sand & Sugar form is a heterogeneous mixture. You can identify tiny sugar crystals and particles of sand if you look closely, 
  • Ice cubes in cola form are the example of a heterogeneous mixture.
