2017年4月27日 · As the electrode potential for bromine is higher, it means bromine should be reduced rather than OHX− O H X − ions. I'm aware that the concentration affects the electrode potentials, but the question simply states 'an aqueous solution of NaBr' with no reference to concentration whatsoever, so I can only assume standard solutions. Also, why do we not look at the electrode potentials of ...

Use the trends in ionization energy and electron affinity to explain why sodium bromide has the formula NaBr and not Na2Br or NaBr2. Which one of the following is the correct statement? a) All metals form 1+ ions and sodium is a metal. b) Sodium only has one electron, so it has only one to lose. c) Sodium has only one valence electron which can be lost relatively easily; removing a …
