Question

When a solute is added to a solution why does it remain homogeneous?

Answer 1

Answer:

                 When a solute is added to a solution, it remains homogeneous because the solute is soluble in given solvent.

Explanation:

                         Homogeneous mixtures, also called true solutions are those mixtures in which the components proportions are same throughout in any given sample. For example, the mixture of table salt (NaCl) and water. When the solution is unsaturated and further NaCl is added to it, it will dissolve the NaCl because the saturation point is still not reached. Remember, as "Like Dissolves Like" NaCl being polar in nature will interact with water molecules and will dissociate into Na⁺ and Cl⁻ ions surrounded by δ- O and δ+ H atoms of water molecules.

Conclusion:

                  In order to form a Homogeneous mixture the solution must be unsaturated, solvent must have affinity for incoming solute particles and the size of solute should be equal to 1 Â (Angstrom).

Answer 2

That is because it dissolves and you cannot see the constituents of the solution. If you added a rock to water, it would be heterogeneous because you could see the elements of the solution, however, here you can't, so it's homogeneous.
