Diluted and concentrated solutions.
Solutions are chemical mixtures, and three words concerning them might be concentration, solubility, or particles.
During an investigation several students make statements about solutions which statement is not true

See http://www.fiu.edu/~pricer/Calcium%20Carbonate.pdf.The solubility of CaCO3 depends on the solubility of CO2. The solubility of gases decreases in water as the temperature rises. This behavior is discussed at http://antoine.frostburg.edu/chem/senese/101/solutions/faq/temperature-gas-solubility.shtml.
According to the degree of solubility, the three types of solution are: isotonic solutions, hypertonic solutions, and hypotonic solutions. These three solutions have different effects on the osmosis of cells.
Pressure can affect the solubility but the effect is not important.

It increases.
Solubility of a solute is the amount of this substance dissolved in a given solvent, at a given temperature and pressure; the solubility is expressed in g/L or g/100 mL.

There are many different types of solutions. Some examples of different solutions are isotonic solutions, hypertonic solutions and hypotonic solutions.
at 20ºC solubility in water is 2g/L and at 50ºC solubility is 5g/L. There is data showing that even with refrigeration, solutions of melatonin are only stable for about a week when containing ethanol. Ethanol is used in preparing solutions due to the higher solubility of melatonin in ethanol. Solubility data is from teh EC report and the stability data is from the Sigma-Aldrich Product Info Sheet.
