Conclusion and Recommendation:
In this experiment, the group was able to determine the solubility of two partially miscible liquids and the group was also able to determine the critical temperature of the solution. Throughout the experiment, there are factors that affect the solubility of the mixtures, the nature of solute and solvent, the temperature and the pressure.
a) Nature of Solute and Solvent
Molecular Size The larger the molecule o the bigger its molecular weight, the less soluble the substance will be.
Polarity Polar solutes will dissolve polar solvents; Non polar solute molecules will dissolve non- polar solvents
b) Temperature
If the solution process absorbs energy, then the solubility will be Increased as the temperature is increased. If the solution releases energy, then the solubility will Decreased with increasing temperature.
c) Pressure
If solid and liquid, there is no change in solubility if pressure changes, likewise, in gas, as pressure increased, solubility also increases.
Cloudiness is significant in this experiment for immiscible liquids. Through cloudiness, we can say that the substance is still unmix due to the presence of stable emulsion, but when a completely clear solution with no trace of cloudiness, we can assume that the substance is mixed
