Wiki User
∙ 13y ago
If the specified ions are both in solution in water, the half reaction is:
SO4-2 + H2O + 2 e-1 => SO3-2 + 2 OH-1.

Formula for copper sulfite?
These are the ions and their charges: Cu+2 SO3-2The charges have to add up to zero, so one +2 copper ion cancels out one -2 sulfite ion. Therefore, the formula is CuSO3.
Why does potassium permanganate and sodium bisulfite form a brown precipitate?
The brown precipitate is MnO2, it is the product of the following redox in neutral environment:For each half reaction:MnO4- + 4H++ 3e- → MnO2 + 2H2O REDUCTIONHSO3- + H2O → SO42- + 3H+ + 2e- OXIDATIONOverall: Permanaganate half reaction x2 + Bisulfite half reactionx32MnO4- + 3HSO3- + 8H+ + 3H2O + 6e- → 2MnO2 + 3SO42- + 4H2O + 9H+ + 6e-Cancelling like terms:2MnO4- + 3HSO3- → 2MnO2 + 3SO42- + H3O+Note that all species are balanced, all charges are balanced and the brown precipitate MnO2 is accounted for. The reaction also predicts that acid is formed in the process.

Is c2h6o o2 balanced?
No! Looks like half a combustion reaction and I do not mean the half reaction method. C2H6O + 3O2 -> 2CO2 + 3H2O

They show the oxidation an reduction half's of a reaction seperately
What are redox half reactions?
A redox half reaction is a reduction or an oxidation reaction. He half reaction does not occur by itself it much be coupled so that he electron released for another to be accepted.
Formula for copper sulfite?
These are the ions and their charges: Cu+2 SO3-2The charges have to add up to zero, so one +2 copper ion cancels out one -2 sulfite ion. Therefore, the formula is CuSO3.
Single reaction where oxidation and reduction take?
half reaction
How and why were Yin and Yang needed to be kept in balance?
The yin and yang needs to keep balanced because in the circle half of it is black and half of it is white so if its not balanced it wont be even.
