Write the overall reaction for the Redox reaction (below) when it occurs in a basic environment. H3ASO4 (aq) + Zn (s) → AsH3 (1) + Zn²+ (aq) Steps for writing half-cell reactions and overall Redox reactions: 1. Balance atoms other than H and O by changing their coefficients 2. Balance the O's and H's by adding OH and/or H₂O 3. Add electrons to balance the charge 4. Add the Oxidation and Reduction equations once the electrons in each cancel out 5. Cancel out (or reduce to the lowest possible numbers) any other species that are present on both sides of the reaction More Information H3ASO4 + AsH3 Zinc + Zinc ions
