Cr2O72- + 6 I- + 14 H+ → 2 Cr3+ + 3 I2 + 7 H2O
This reaction needs an acidic medium:
Cr2O7-2 + I- + H+ ----> Cr3+ + I2 + H2O
Iodate and acidified KI are often used together.
IO3- + 5 KI + 6H+ = 5K+ + 3I2 + 3H2O
So2 + i2 + 2h2o -> h2so4 + 2hi
ethanal
ethanol is converted into acetic acid....
Cr2O72- + 6Fe2++ 14H+ --> 2Cr3+ + 6Fe3+ + 7H2O

copper iodide
the reaction between bleach anb potassium iodide is KI+NaCl2--->KCl2+NaI
ethanal
ethanol is converted into acetic acid....
Yes, I know strontium iodate does.
K2Cr2O7 + Na2C2O4 --> K2C2O4 + Na2Cr2O7
Cr2O72- + 6Fe2++ 14H+ --> 2Cr3+ + 6Fe3+ + 7H2O
acetone does not react with potassium dichromate
potassium

copper iodide
The calcium iodide is obtained by the reaction between calcium carbonate (CaCO3) or calcium oxide (CaO) and the hydroiodic acid (HI), not by a direct reaction of the elements.
Assuming a double displacement reaction. 2KI + BaS --> K2S + BaI2
