Question
The size of homogeneous particles is_________.
- Less than 1 nanometer
- More than 1 nanometer
- Less than 10 nanometers
- More than 10 nanometers
Hint:
Less than 1 nanometer
The correct answer is: Less than 1 nanometer
A solution is a homogeneous mixture. The particle size is less than 1nm in solutions. Centrifugation or decantation cannot separate the solutions into their constituents.
