Question 35

Sugar forms clear solution but soap forms cloudy solutions. Why?


Correct Answer: 0

Solution

PLACEHOLDER ANSWER - the answer is an explanation. Sugar dissolves as individual molecules smaller than 1 nm, forming a true solution that does not scatter light, so it is clear. Soap molecules cluster together into micelles of colloidal size (about 1 to 1000 nm). These particles scatter light (the Tyndall effect), so the soap solution looks cloudy.
