Consider the acid-base reaction that occurs when benzoic acid is extracted with aqueous sodium hydroxide.
A.) Write the equation for this reaction, labeling the acid, base, conjugate acid, and conjugate base
B.) Based off the polarity, what is the anticipated relative solubility of benzooic acid and its conjugate base in diethyl ether.
Compute the enthalpy change for this reaction per mole of this substance and dissolves via the reaction and the temperature of the solution rises to twenty eight degree celsius.
