Concentration, Temperature, and Solubility of Salts

Lab 1 Brown 2

Introduction:

During this lab, there will be testing the difference between types of compounds and

solutions. The types of solutions include saturated, unsaturated, and supersaturated. The type of

solution is determined by how much salt or solute it absorbs. A saturated solution is when the

solute dissolves until it cannot anymore. Similarly, to a saturated solution, there can be a

supersaturated solutions which is caused by a solvent absorbing more of a solute than it can hold

normally. On the other hand, an unsaturated solution is when a solution does not absorb its

maximum capacity and it is able to dissolve more (Libertexts, 2020).

The next step is understanding the difference between heterogenous and homogenous

mixtures. Heterogeneous mixtures are a type of mixture that you can physically see different

parts within the mixture or combination. A basic example of a heterogenous example would be a

peperoni pizza. On the pizza, we can see the pepperonis, cheese, sauce, and crust. Opposite of a

heterogenous mixture there are homogeneous mixtures. This is when you cannot see the different

parts of a mixture, all the parts combine and become one substance. An example of a

homogenous mixture would be salt water. The salt is mixed into the water and dissolves into the

water where it is not seen separately (Ophardt, 2020).

I hypothesis that each of the different solutions will require a different amount of solute

to become saturated. I think that salt requires the most. I think that if there is less water, then it

will require less of the solute in order to become saturated.

Methods and Materials:

To begin the lab, obtain 0.1 liters of water. Begin by adding cobalt (II) nitrate until the

solution becomes saturated. Now record the amount of solute it requires to saturate the solution.
