O (6) Which species can be oxidized by Ca2+(aq)? If none, leave box blank.

Answer 1

If El value is more positive, then it is the oxidising a agent, if Evalue is more negative, then it is the reducisa agent com . lotus prodam Half reaction Br2 (l) + 2 + 2 BPO- (aq) 1.osov Cd2+ (aq) +20 Cd (1) - - 0.403v . z 2+ (aq) +20 + m - 0.763 v - The strongest oxidising agent u Br2 27 Weakest oxidising agent is zu 2+ 3 The weakest reducing agent is Br 47 .
