Question
A heterogeneous mixture where the particles do not dissolve but float in the solution is called
- Solution
- Colloids
- Suspension
- Alloys
Hint:
Suspension
The correct answer is: Suspension
- In chemistry, a suspension is a heterogeneous combination of a fluid containing solid particles large enough to cause sedimentation. The particles can be viewed with the naked eye, must be larger than one micrometre in size, and will settle gradually, but the combination is only called a suspension if the particles have not settled out.
- In a suspension solute particles do not dissolve but rather float freely in the media. Mechanical agitation, as well as the addition of excipients or suspending agents, aid in the distribution of the internal phase (solid) in the external phase (fluid).
