note CODATA HBr	Vanderzee 1963, Roth 1937, and Thomsen 1882 measured {HBr } -> {H+ } + {Br- }, Delta_sol_H of HBr as -85.12 +- 0.04 kJ/mol, CODATA Key Vals gives Delta_f_H (Br- ) as -121.41 +- 0.15 kJ/mol, and Delta_f_H (H+ ) = 0 by definition; hence Delta_f_H (HBr ) = 85.12 - 121.41 kJ/mol = -36.29 +- 0.16 kJ/mol
