Answer #1

o answer the following questions. Briefly explain your answer.

a) which cobalt ion, Co2+or Co3+, will oxide Sn to Sn2+?

Co2+

=========================================================b) will dichromate ions oxide H2O2 or to O2?

Manganate(VII) particles, MnO4-, oxidize hydrogen peroxide, H2O2, to oxygen gas.

The response is finished with potassium manganate(VII) arrangement and hydrogen peroxide arrangement fermented with weaken sulphuric corrosive.

Amid the response, the manganate(VII) particles are decreased to manganese(II) particles.

====================================================================

c) To obtain Mn2+ using CI- as a reducing agent, should you use MnO2 or MnO4-?

MnO4-           --answer

5Cr3+ + 3MnO4 - + 8H2O → 5CrO4 2- + 3Mn2+ + 16H+
