cr2o7^-2+c2o4 gives co2+cr^+3 solve equation in basic medium
I'll so this in two half equations and let you add them.
Cr2O7^2- + 6e + 7H2O ==> 2Cr^3+ + 14OH^-
C2O4^2- + ==> 2CO2 + 2e
--------------------------------------------------------------
Multiply equation 1 by 1 and equation 2 by 3 then add the two half equations for the full net ionic balanced equation. Cancel the electrons on the two sides. ALWAYS check the final equation to make sure it is balanced. It MUST balance three ways.
1. atoms must balance
2. total electron loss must equal to electron gain
3. charge on the left must balance with change on the right.
