Question

Balance the following equation representing reactions thatoccur in a basic solution. Cr(OH)3(s) +IO3(-)(aq) -->CrO4(-2)(aq) + I(-)(aq) (The (-2) or (-) are the charges of the atom) Balance the following equation representing reactions thatoccur in a basic solution. Cr(OH)3(s) +IO3(-)(aq) -->CrO4(-2)(aq) + I(-)(aq) (The (-2) or (-) are the charges of the atom) (The (-2) or (-) are the charges of the atom)

Explanation / Answer

Break the equations into its half reactions and balance thme withthe following 4 rules 1) Balance the element 2) Balance O with H20 3) Balance H with H+ 4) Balance charge with e- Cr(OH)3--->CrO4(-2) Cr(OH)3+H20--->CrO4(-2) Cr(OH)3+H20--->CrO4(-2) +5H+ Cr(OH)3+H20--->CrO4(-2) +5H+ + 3e- i) IO3(-)--->I(-) IO3(-)--->I(-)+3H20 IO3(-)+6H+ + 6e---->I(-)+3H20           ii) Now add i and ii but dont forget to times i by 2 so u have 6e- andthey cancel out when u add the equations. Always cancle out theelectrons
