Question

Some metals exhibit magnetic properties. In the lab a student immersed a strips of Co(s). Nd(s), Sm(s) and Y(s) in aqueous solutions of the metallic ions. The following results were obtained: Co2+(aq) + Nd(s) – Co(s) + Nd2+(aq) y3+ (aq) + Nd(s) - no reaction Sm2+ (aq) + Y(s) no reaction List the oxidizing agents from strongest to weakest. Sm(s) > Y(s) > Nd(s) > Co(s) Co2+ (aq) > No2+(aq) > Y3+(aq) > Sm2+(aq) Co2+ (aq) > Sm2+(aq) > Y(s) > Nd(s) Co(s) > Nd(s) > Ys) > Sm(s) Sm2+(aq) > y3+(aq) > Nd2+(aq) > Co2+(aq) Click Save and Submit to save and submit.

Answer 1

orowa aras aq) As he can oxcidise Holythen cone stranger oxidising agent than Md 2" (). As You can not oxidise Naksythen Y 37 is weaker oxidising agent than Nola (aq). As sunt can not oxidise Yo then sim 2 ) is weaken oxidisting agent than Y 3 lazy :. The onder of oxidising agents from strongest to weakest is → Co2+ (aq.) > No2+ (aq) > Y3+ (aq) > Sm2 (aq) (option-B) G
