In the balanced chemical reaction
`IO_(3)^(ө)+aI^(ө)+bH^(ө)rarrcH_(2)O+dI_(2)`
`a, b,c`, and `d`, respectively, correspond to

Options

A. 5, 6, 3, 3
B. 5,3,6,3
C. 3, 5,3,6
D. 5, 6, 5, 5

Answer

A

Explanation

(a) The balanced equation is
`12H^(+) +10e^(-) +2IO_(3)^(-) rarr I_2+ 6H_2O`
`underline(10I^(-) rarr 5I_(2) +10e^(-))`
`underline(10I^(-) +12H^(+) +2IO_(3)^(-) rarr 6H_2O + 6l_2)`
or `51^(-) +6H^(+) + IO_(3)^(-) rarr 3H_2O + 3I_2`
(a) (b) (c) (d)
