A suspension of sodium dodecanoate,CH₃(CH₂)₁₀COONa,in water is most likely to form what type of colloid? A)hydrophilic colloid B)association colloid C)emulsion D)aerosol E)hydrophobic colloid

Question

Quizplus · Accepted Answer

The given compound sodium dodecanoate contains both hydrophilic (COO-Na+) and hydrophobic (CH3-(CH2)10-) parts. Therefore, it can form an association colloid, where the hydrophilic part of the molecule interacts with the water molecules, and the hydrophobic part forms micelles, which are dispersed in water.
