Question

According to the data booklet Cu(NO3)2 and Sn(s) are spontaneous Cu2+ being a strong reducing agent and Sn(s) being a strong oxidizing agent

but according this lab:
d2l.adlc.ca/content/ADLC-Depts/ScienceSH/SCN3796-5cBl-08Feb10/chemistry_30/mm/m3/m3_l3_testing_predictions/m3_l3_testing_predictions.html

According to this there was no reaction between Cu(NO3)2 and Sn(s)

Is it because there isnt much of a potential difference between the two?

Help plz!

and thank you in advance

Answer 1

I didn't look at the site but there is a lot of misinformation floating around out there. #1, Sn is a reducing agent, not an oxidizing agent. #2, Sn + Cu^+2 ==> Sn^+2 + Cu will occur spontaneously. You can take that to the bank.
