As the title of the lab suggests, the purpose of this lab is to measure the solubility
of borax and other properties or quantities related to the thermodynamics of the borax solvation
reaction. We found the concentration of dissolved Borax used in each beaker in the experiment.
Then, by drawing a graph of the reciprocal of temperature against the natural logarithm of the
equilibrium constant, we found the enthalpy and entropy of borax using the slope and intercept.
The effect of the thermodynamic quantities enthalpy and entropy will give
Gibbs free energy. This can be done by subtracting the product of temperature and entropy from
enthalpy. Through the value of Gibbs free energy, we can determine whether or not a reaction
can occur spontaneously or not. If the free energy is less than 0 then the reaction is spontaneous
and vice-versa. The direction in which a reaction proceeds can also determine by the value of the
equilibrium constant. If K is greater than 1 then the reaction is spontaneous and will proceed to
produce products.
