Answer is 5K2Cr2O7-I-x2212-H-x2192-I2CuSO4-I-x2212-x2192-I2H2O2-I-x2212-x2192-I2Cl2-I-x2212-x2192-I2HNO3-I-x2212-x2192-I2

Consider the following list of reagents:
Acidified $K_{2} {C r}_{2} O_{7}$ , alkaline $K M n O_{4}, C u {S O}_{4}, H_{2} O_{2}, {C l}_{2}, O_{2}, F e {C l}_{2}, H {N O}_{3}$ and ${N a}_{2} S_{2} O_{3}$ . The total number of reagents that can oxidise aqueous iodide to iodine is:

Answer is 5
$K_{2} C r_{2} O_{7} + I^{-} + H^{+} \to I_{2}$
$C u S O_{4} + I^{-} \to I_{2}$
$H_{2} O_{2} + I^{-} \to I_{2}$
$C l_{2} + I^{-} \to I_{2}$
$H N O_{3} + I^{-} \to I_{2}$
