i was reviewing previous exams for my final analytical exam and i blocked at this exercise that says :
given the standard electric potential of bromine couple : bro3- (1.47v) , hbro(1.60) br2(1.08) br- .
determine which degree of oxydation can exist dominant in an aqueous solution at ph=0
so i thought of using nenrt potential but i dindnt know how to establish the dominant form

Draw an oxidation state diagram (Frost diagram). What does that tell you?
