Question

a sample of water is mixed with a surfactant what will most likely happen to the viscosity of the water

Answer 1

The viscosity of water will decrease as it is directly related to intermolecular forces and when intermolecular forces decrease viscosity decreases.

Answer 2

If a sample o water is mixed with a surfactant, the most likely result is that the viscosity of the water will increase. This is because of the property of the surfactant which is generally viscous; and becomes more viscous when mixed with water.
