REDOX Reactions (Acidic vs Basic)

Postby Mirna_Velasco_1L » Sun Feb 05, 2017 7:54 pm

If a problem given does not tells us that the redox reaction is an acid or a base, How can we tell? While doing the homework problems, I noticed that for Acid half-reactions, we balance the O's and the H's with H2O or H+ and for bases we Balance the half reactions by adding H2O to both sides of the equation, and the OH- to one side. Is this process correct? Also if a compound like HClO is given, do we assume that the overall charge is zero?

From the textbook:
1) separate the half reactions.
2) balance the non Hydrogen and Oxygens (usually the metal)
3) balance the Oxygens by adding water on the opposite side.
4) balance the Hydrogens by adding protons or hydroxide anions
5) balance the charges by adding electrons to the appropriate side so that the overall charge of the reaction is zero.

And yes, if it is not specified that the species is charged, it is assumed that it has neutral charge.
