In iodometric estimation of `Cu^(2+)` ion, the following reaction took place
`2Cu^(2+)+4ItoCu_(2)I_(2)+I_(2)`
`I_(2)+2Na_(2)S_(2)O_(3)to2NaI+Na_(2)S_(4)O_(6)`
If 100mL OF `CuSO_(4)` solution added to excess KI requires 50mL of 0.2M `Na,S_(2)O_(3)` the molarity of `CuSO_(4)` solution is :

Find the n factor of Na_(2) S_(2) O_(3) in the following reactions. Na_(2) S_(2) O_(3) + I_(2) rarr NaI + Na_(2) S_(4) O_(6)

There are two types of iodine titrations (a) Iodometric & (b) Iodimetric, Iodometric method is indirect method of I_(2) estimation. Any oxidant which liberates I_(2) from KI solution, the liberated iodine is estimated by titrating it with Na_(2)S_(2)O_(3) solution as : I_(2)+2Na_(2)S_(2)O_(3)rarr2NaI+Na_(2)S_(4)O_(6) 100 mL of .x. M K_(2)Cr_(2)O_(7) solution is added to excess of KI solution in acidic medium. The liberated iodine required 50 mL of 0.1N Na_(2)S_(2)O_(3) solution. The value of x is

For the following reaction I_(2)+2Na_(2)S_(2)O_(3)rarr2NaI+Na_(2)S_(4)O_(6) The incorrect statement is
