Here all statements are correct here regarding HI as follows 2KMnO4+3H2SO4+10HI arrow K2SO4+2MnSO4+8H2O+5I2 H2SO4+2HI arrow SO2+I2+2H2O HIO3+5HI arrow 3I2+3H2O 2CuSO4+4HI arrow 2CuI2+2H2SO4 2CuI2 arrow Cu2I2+I2

Q. Pick out the correct set of statements for HI. 1. It reduces iodic acid to I2​ 2. It reduces H2​SO4​ to SO2​ 3. It decolourises acidified KMnO4​ 4. It liberates I2​ with CuSO4​ solution

1, 2, 3, 4

Here all statements are correct here regarding HI as follows 2KMnO4​+3H2​SO4​+10HI→K2​SO4​+2MnSO4​+8H2​O+5I2​ H2​SO4​+2HI→SO2​+I2​+2H2​O HIO3​+5HI→3I2​+3H2​O 2CuSO4​+4HI→2CuI2​+2H2​SO4​ 2CuI2​→Cu2​I2​+I2​

Q. Pick out the correct set of statements for HI.

$1.$ It reduces iodic acid to $I_{2}$

$2.$ It reduces $H_{2} S O_{4}$ to $S O_{2}$

$3.$ It decolourises acidified $K M n O_{4}$

$4.$ It liberates $I_{2}$ with $C u S O_{4}$ solution
