Find the sum of the coefficientsa, b, c and d,
in the given balanced chemical reaction,IO3-+aI-+bH+cH2O+dI2

Answer:
17.00
Solution:

IO3+ aI+ bH+cH2O + dI2

Step 1:I1I2oxidation 

IO3I2reduction 

Step 2:2IO3+ 12H+I2+ 6H2O

Step 3:2IO3+ 12H++ 10eI2+ 6H2O

2I I2+ 2e

Step 4:2IO3+ 12H++ 10eI2+ 6H2O

2II2+ 2e5

Step 5:2IO3+ 10I+ 12H+6I2+ 6H2O

IO3+ 5I+ 6H+3I2+ 3H2O

On comparing,a = 5, b = 6, c = 3, d = 3
