Answer 2

The correct observation is- C. a translucent solution is formed.

• When starch is mixed with the water, a colloidal solution is formed. A colloidal solution is a heterogeneous and translucent solution.
• Particles of the colloidal solution are not visible through the naked eye and hence, it is difficult to separate them through physical methods such as filtration.
• However, it shows the Tyndall effect as they scatter light when it is through them.
