Basic or acidic solution?

Postby HannahNizinski_1G » Mon Feb 01, 2016 10:45 am

When balancing redox reactions will the question indicate whether the reaction is in a basic or acidic solution? If not, how can we determine this?

I think the question will indicate that.

I don't think you would need to know the pH of the solution for redox reaction. It usually does not matter.

How do we determine whether we use OH- or H+ to balance the equation with?

Use H+ when the reaction is in an acidic solution, and use OH-/H20 when the reaction is in a basic solution.

Use H+ when the reaction is in an acidic solution, and use OH-/H20 when the reaction is in a basic solution.

Actually you can use H+/H2O when the reaction is in acidic solution and OH-/H20 if basic. Just rember never let H+ and OH- appear in a single half reaction, except the solution is neutral and you have to.
