Which of the following statements is NOT correct regarding mixtures? |
Colloids are heterogeneous mixtures in which the particle size is large. The major component of a solution is called the solvent.
The minor component of a solution is called the solute.. A solution is a homogeneous mixture of two or more substance . |
Colloids are heterogeneous mixtures in which the particle size is large. |
The correct answer is option 1. Colloids are heterogeneous mixtures in which the particle size is large. The statement that is NOT correct regarding mixtures is: Colloids are heterogeneous mixtures in which the particle size is large. Colloids are indeed heterogeneous mixtures, but the key characteristic is that the particle size is intermediate between those of solutions and suspensions. In colloids, the particles are larger than individual molecules in a solution but smaller than the particles in a suspension. The distinguishing feature of colloids is that the particles do not settle out, and they scatter light, giving the mixture a milky or cloudy appearance. |
