Question
Which produces the better cleaning action-clear water or soap solution?
Solution
Soap solution produces the better cleaning action than clear water. Surface tension of soap solution is less as compared to that of clean water.
Therefore, the molecules of soap solution can penetrate more into the fine pores of the cloth, making the cleansing action more effective.
