In the analysis of the B4O5(OH)4^2- concentration in one of the 5-mL borax samples, suppose that the bromocresol green endpoint was surpassed. How does this affect the reported solubility product of borax at that temperature? Explain. Temperatures can range from 4.4 degrees C, 17.1 degrees C, 34.6 degrees C, 41.6 degrees C, and 50.6 degrees C.

Solution

The surpassing of end point of bromocresol results in the increasing the solubility product of borax as the removal of moles of end product will drive the equation foward as the K of the reaction is lowered .
