Question

The values of coefficients to balance the following reaction are
`Cr(OH)_(3)+ClO^(-)+OH^(-) rarr CrO_(4)^(2-)+Cl^(-)+H_(2)O`
A. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 3"," 3","3"):}`
B. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 4"," 3","2"):}`
C. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 4"," 4","2"):}`
D. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 3"," 2","3"):}`

Answer 1

Correct Answer - D
`{:(Cr(OH)_(3)+5OH^(-)rarrCrO_(4)^(2-)+4H_(2)O+3e^(-)"]"xx2),(ClO^(-)+H_(2)O+2e^(-)rarr Cl^(-)+2OH^(-)"]"xx3):}/ul(2Cr(OH)_(3)+4OH^(-)+3ClO^(-)rarr2CrO_(4)^(2-)+3Cl^(-)+5H_(2)O)`
