Enthalpy and Entropy Changes of Dissolving Borax
Plot your values of ln(Ksp) vs. 1/T
and find the slope and y-intercept of the best fit line.
Use the equation for the best fit line and the following
equation
ln(K)=−ΔH∘RT+ΔS∘Rln(K)=−ΔH∘RT+ΔS∘R to calculate ΔH° and
ΔS° for dissolving Borax

Borax, sodium tetraboratedecahydrate, is an important mineral found in dry lakebeds in California. It is used to make soap and glass and used as a preservative. You can use the values of Ksp (solubility-product constant) of borax at different temperatures to determine ΔH∘, ΔS∘, and ΔG∘ for the dissolution of borax: Na2B4O5(OH)4⋅8H2O(s)(borax)→2Na+(aq)+B4O5(OH)42−(aq)(tetraborate)+8H2O(l) The relationship ln(Ksp)=−ΔH∘RT+ΔS∘R has the form of a linear equation, y=mx+b, where y is lnKsp and x is 1/T. The slope (m) is equal to −ΔH∘/R, and the...
