The mixture of Blood plasma, Metal alloys, etc are pure example of ______________________ mixture.

Key Points

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. 

• Homogeneous mixture:
  • A homogeneous mixture is a liquid, gaseous & solid mixture.
  • Throughout any given sample, it has the same proportions of its components 
  • The mixture has the composition throughout & the same uniform appearance in every step
  • Many homogeneous mixtures are generally referred to as solutions.
• Example:
  • Some examples of homogeneous mixtures:
    including air, mixture, saline solution, most alloys, bitumen, blood plasma, etc.​

​Mistake Points

• The question asks about 'blood plasma' and not 'blood', which are not the same.
• Blood plasma is a light yellowish liquid that forms about 55% of blood.
• Blood comprises blood plasma and the blood cells like RBCs, WBCs, etc.
• Therefore, blood plasma is a homogeneous mixture, while blood is a heterogeneous mixture.
