Basic conditions

Postby WYacob_2C » Sat Feb 22, 2020 2:32 pm

How do we go about balancing redox reaction in basic solutions? How different is it from having a redox reaction in acidic reaction? Thank you in advance.

When you balance a redox reaction in basic solutions, you use H20 and OH- on each side of the half reaction, whereas when in an acidic solution, you use H20 and H30+. To determine whether to use H20 vs. its protonated/deprotonated form, see whether you need more O or more H on either side of the equations.

In a basic solution you add OH- to balance H and in an acidic solution you add H+

My TA also said that if the problem mentions alkali you use OH-.

In a basic solution, you would use hydroxide (OH-) to balance out the hydrogens (H). This is different from acidic solutions, in which you would use (H3O+) to balance out any hydrogens (H).

its the same as acidic solution expect you balance out the H+ with OH-

In an acidic solution, you add H+ to balance the hydrogen in the equation. In a basic solution, however, you add OH- to balance the hydrogens (and then add H2O to balance that change in oxygen).
