Hint: First let’s discuss what colloid is. So, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles are suspended throughout another substance. Salt water is a true solution and is not a colloid. It is a true solution since salt particles completely dissolve in water.

Complete answer:
A solution is a mixture of a solvent and solutes. In the solution of seawater, water is the solvent. The hydrogen and oxygen atoms in water molecules make up about \[96.5\] percent of the mass of seawater. So, Salt water is a true solution and is not a colloid. It is a true solution since salt particles completely dissolve in water
Ocean water is the type of mixture called a solution, because the salt is dissolved in the water. Water is the solvent, and sodium chloride is the solute. Water dissolves salt when water molecules attract and pull apart the sodium and chloride ions in salt crystals.
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Note:
Salt water can be separated into its parts. You can let the water evaporate, and you will have just the salt left. Salt water is a solution because it has these two characteristics: it has the same concentration of each of its parts throughout the solution, and it can be separated by some physical process.
