Chapter 19, Problem 16TE
How necessary is soap for removing salt from your hands? Why?
Expert Solution & Answer
To determine
Whether soap should be used for removing salt from hands
Answer to Problem 16TE
The soap is not necessary for removing salt from hands. The water can remove the salt as strong ion-dipole interactions are present between them.
Explanation of Solution
The soap contains polar as well as non-polar components. So, it can be used for removing the non-polar dirt materials which cannot be removed by just water.
The salt molecule is polar. The water molecule is polar. It exhibits dipole. Like dissolves like. So, water can remove the salt molecules from the hands.
The water and salt molecules exhibit ion-dipole interactions between them. The ion-dipole interactions are strong.
So, only water is enough for removing the salt, and soap is not required.
Conclusion:
Therefore, the soap is not necessary for removing salt from hands. The water can remove the salt as strong ion-dipole interactions are present between them.

- A bungee jumper plans to bungee jump from a bridge 64.0 m above the ground. He plans to use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 6.00 m above the water. Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge. (a) What length of cord should he use? Use subscripts 1 and 2 respectively to represent the 5.00 m test length and the actual jump length.
