Question

Which of the following is correct about true solutions?

• A. Homogeneous mixtures with particle size < 1nm
• B. Heterogeneous mixtures with particle size < 1nm
• C. Homogeneous mixtures with particle size > 1nm
• D. Heterogeneous mixtures with particle size > 1nm

Answer 1

The correct option is A Homogeneous mixtures with particle size < 1nm

A solution has the following properties:

• It is homogeneous.
• It has tiny solute particles of size < 1 nm. Thus, it cannot scatter light.
• It cannot be separated by filtration.
