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

When a solute is added to a solution it remains homogeneous because the solute dissolves and is evenly distributed among the solution.

For a solution to not be homogeneous it must have distinguishable parts that  are different from the base of the solution. As an example, a salad would not be a homogeneous solution because you can distinguish the different parts just by looking at it.

An example of a homogeneous solution would be salt water because the salt completely dissolves into the water.

Hope this helps and have a nice day! :)

Because of the intermolecular space present in the solution,the solute gets dissolved in these spaces hence,making it uniform throughout the solution.

c is the answer because when something is left after something evaporates that shows the chemical change.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
