Balancing Redox Equations in Acid
|Step 1:||Separate in half reactions.|
|Step 2:||In each half reaction, balance all elements except O & H.|
|Step 3:||Balance O by adding H2O.|
|Step 4:||Balance H by adding H+.|
|Step 5:||Balance charges by adding e-.|
|Step 6:||Multiply all coefficients in 1 or both half reactions by an integer to get the number of e- in the two half reactions equal.|
|Step 7:||Add the 2 half reactions together & cancel out any species that appear on both sides of net reaction.|
|Step 8:||Check that charges and atoms are balanced.|
