Today we will learn about Density and what Saturated Solutions are!
So let's go with the Concepts:
Density is a quantity that allows us to measure the amount of mass in a substance.Source
A saturated solution is a chemical solution that contains a maximum concentration of solute dissolved in a solvent. Source
Let's see what we need?
- A transparent glass
- A spoon
What do we have to do?
- The first thing we have to do is put a little water in the glass and add a few drops of ink, we will notice
- Next we create a Saturated Solution that is nothing more than placing a little water in the glass and adding salt until it no longer dissolves at that moment we can say that we create a saturated solution.
- Once this is done we place a few drops of ink and we will notice how they remain on the surface for longer and that they do not penetrate the solution as quickly.
In the second case, the density of the saturated solution is greater than that of the ink, therefore the drops remain on the surface, the drops when falling into the solution cannot penetrate and are returned to the surface delaying the diffusion throughout the glass .
