Example 11.1 Calculate the enthalpy for each step in the bromination of ethane by bromine atoms from molecular bromine. Determine the overall enthalpy of the reaction. 

Quenching methods have been used to analyze inorganic anions. Thus, halide ions have been analyzed using indicator fluorescence quenching, with iodide being the most efficient quencher and chloride the least effective. In the same way, electrophilic bromination of fluorescein to yield the low fluorescent 1,3,6,8-tetrabromofluorescein has been used for bromine determination, and a displacement reaction using a nonfluorescent Hg metal chelate has been described for sulfide determination.
