Redox Equations in Chemistry???

Question

When you do redox you either have H+ or OH-..when you have an equation that has OH- do you do it the exact same way as the H+ or do you use different steps?
ex.Bi (+3) +SnO(+2)-------> Bi+SnO(-2)

Answer 1

No you don't respectively within Acidic solution redox reaction are done differently than in basic solution(OH-):

In Acidic solution(that is with the H+) we would do your above equation as such,

Balance the other Atoms other than hydrogens and oxygens which is already done then

Balance number of oxygens, then add H, then electrons repectively thereby

Whereas in basic solution(OH-) you would do all the steps for the H+ one except when you add the H+ to balance a particular side after balancing oxygen in terms of H2O, you would also add as many OH- as H+ added on each side of the equation except where H+ is present you the H+ and the Oh- would add to make H2O and then reduce H20 on both side,

say basic solution

8H+ are added------------------4H20

then

8H+ and add 8OH---------------------4H2O and add 8Oh- on this side too

H+ and OH- add to make water

8H20-------------------4H2O and 8OH-

reduce H20s

4H2O-----------8OH-

balance charge by adding electrons

8e- + 4H2O--------------8OH-

Answer 2

The OH- and H+ depends if your reaction is taking place in an acidic environment or if the environment is basic. Should be told to you. You can't just add H+'s and OH-'s. So when you get problems in acidic or basici enviroment, you need to balance the equation with H2O that's how you can figure out how many H+'s or OH-'s you have and you also need to take the charges into account.

Answer 3

All chemical equations are solved using the periodic table, so you can know wht the oxidation # is for that element, before you begin to balance it. And you can't take an EXAM without a periodic table in hand, unless you are Einstein, and have memorized the WHOLE chart!

Answer 4

use diffrent steps.
