This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.
Video Topics
When a solute is dissolved in a solvent the BP is elevated and the FP is lowered.
This effect comes from dilution.
dTf = iKfm
dTb = iKbm
dT is the change in BP or FP or (Tsolution - Tsolvent)
K is a constant C/m
Kb should be positive and Kf should be negative.
m is the molality of the solute
