Hydrogen iodide is even more easily oxidized than hydrogen bromide. Therefore,
for similar reasons to those already given for hydrogen bromide (q.v.),
preparation of HI from an iodide and concentrated sulfuric acid is not possible. As
in the ...

Figure 1 1.2A Bodenstein's results for a set of experiments at 448 °C From
dissociation of 1 mol HI and from combination of 0.5 mol H 2 + 0.5 mol 1 2 the
mixtures of HI, H2 and I2 obtained have the same composition pure hydrogen
iodide, and ...
Most of the water vapor in the hydrogen iodide gas is removed by the apparatus
just described. The gas can be obtained entirely free of water vapor by attaching
a glass tube filled with anhydrous calcium chloride to the end of the train of gas- ...
Hence we see that for this reaction the dimensions of K are those of a pure
number: (moles/literXmoles/liter) Dimensions of K = ; — ----- = 1 (moles/liter)-
When hydrogen iodide decomposes, equal numbers of molecules of hydrogen
and iodine ...

475), a considerable amount of heat is developed in the formation of hydrogen
chloride, but a less amount in the formation of hydrogen bromide, and the
production of hydrogen iodide from its elements involves the absorption of heat.
We have ...

and iodine Hydrogen chloride can also be made by the similar reaction of
concentrated sulphuric acid on sodium chloride: NaCl(s) + H2SO4(1) NaHSO4(s)
+ HCl(g) However, hydrogen bromide and hydrogen iodide are oxidised by
sulphuric ...

Decomposition and Isomerization of Organic Compounds
Step A RI —> HI+olefin Step B I+ RI -+ I+HI+o1efin Step A corresponds to a direct
unimolecular elimination of hydrogen iodide and Step B to a concerted
mechanism for which the activation energy exactly equals the overall
endothermicity.

In the last case, the dangerous character of the reaction of the preparation of
hydrogen iodide by distillation of the phosphorus/moist iodide mixture was also
mentioned. The formation of phosphonium iodide often causes the conduits of
the ...

Hydrogen iodide being a stronger reducing agent than hydrogen bromide,
cannot be prepared by heating an alkali iodide with sulphuric acid. The latter is
simultaneously reduced to sulphur dioxide, sulphur or hydrogen. However,
hydrogen ...

The reaction order tells us how the reaction rate is related to the concentration.
As another example, consider the reaction of hydrogen and iodide to produce
hydrogen iodide: H„ , + L . -> 2H1, , 2(g) 2(g) (g) The rate law for this ...
