What are some examples of solutions?
If you make Kool-Aid, the Kool-Aid crystals are the solute. The water is the solvent, and the delicious Kool-Aid is the solution.
The solution is created when the particles of the Kool-Aid crystals diffuse throughout the water.
The speed of the diffusion process depends on the temperature of the solvent and the size of the solute particles.
Higher temperatures in the solvent will increase the rate of diffusion.
However, we do not like hot Kool Aid. Therefore we increase the energy of the solvent by stirring the mixture adding kinetic energy and moving the particles throughout the solution.
The concentration of the solution is determined by how much solute is dissolved in the solution. You can change the concentration of the Kool-Aid by increasing or decreasing the amount of Kool-Aid, making the drink sweeter more concentrated or less sweet.
But solutions do not only take place in liquids. Have you ever been in an elevator with an individual who has doused themselves in perfume or cologne. In this example the air of the environment acts as the solvent and the cologne or perfume particles are the solute.
I hope this was helpful.
