A solutuion is prepared by adding 40 grams of NaC1 to 100 grams of water at 80 degrees Celcius. Describe this solution.
saturated salt solution with some solid salt left in the bottom. Solubility is 38.47 grams NaCl for 100 grams water.

To describe the solution, we first need to understand what happens when sodium chloride (NaCl) is added to water and heated.
When NaCl is dissolved in water, it forms a homogenous mixture called a solution. NaCl is an ionic compound made up of positive sodium ions (Na+) and negative chloride ions (Cl-). Water molecules are polar, meaning they have a positive end (hydrogen) and a negative end (oxygen). When NaCl is added to water, the polar water molecules surround the Na+ and Cl- ions, separating them from each other and thus dissolving the salt.
Now, let's break down the given information:
- 40 grams of NaCl is added: This means that 40 grams of solid NaCl are mixed with water.
- 100 grams of water: This refers to the amount of water used as a solvent in the solution.
- 80 degrees Celsius: This is the initial temperature of the water before adding the NaCl.
Considering the solubility of NaCl in water increases with temperature, and assuming complete dissolution occurred, we can describe this solution as a saturated sodium chloride solution at 80 degrees Celsius.
A saturated solution means that the maximum amount of solute (NaCl) has been dissolved in the given solvent (water) at the particular temperature (80 degrees Celsius). At this point, if more NaCl were added, it would not dissolve and would remain as solid particles at the bottom of the container.
