Need to get Tb+3 in products; can it be written as 2Tb(SO₄)₂+Zn--(H₂SO₄)->Tb₂(SO₄)₃+ZnSO₄?

Tb₄+ + e- => Tb₃+ Reduktion

Zn => Zn₂+ + 2e- Oxidation

Combination is:

2 Tb₄+ Zn => 2 Tb₃+ + Zn₂+

Sulfate and sulfuric acid are spectatorion will not change

Code: Select all

2 Tb&#40;SO4&#41;2 + Zn => Tb2&#40;SO4&#41;3 + ZnSO4
