H+ or H2O

Postby Sophia Dinh 1D » Sun Mar 01, 2020 2:12 pm

When do you add H+ rather than add H2O?

You would first have to add H20 in order to balance the O's and then add H+ to balance the H's.

One of the rules our TA taught us regarding this was that it's based off what type of reaction you have.

If it's acidic, balance O with water, then balance H with protons

If it's basic, balance O with OH-, and H with H20

You first have to add H20 to balance the O’s. Then, in an acidic solution you just add H+ to balance the H’s . Whereas in a basic solution you either add H+ and balance it with OH- to create H20 or you add an H20 for every 2 OH- molecules on the other side in order to balance the hydrogens.

H2O is used to intially balance the oxygens, then H+ to balance the hydrogens, and then e- to balance the charge.

You can use both H+ and H2O to balance redox reactions when they occur in acidic solutions.

this is a way simpler way to think about it than the worksheet, thanks!

You balance the oxygen first by adding water and then you balance H+ if it is an acidic environment.

Depends what type of solution you it is occurring in.

Yeah, it really depends if the solution is neutral, basic, or acidic.
