Question

In the exchange process, ${H_2}S$ gas is passed through cold water, the hydrogen atoms in ${H_2}S$ exchange with deuterium from ${D_2}O$ present in water. Thus, ${H_2}S$ becomes ${D_2}S$. If this true enter \[1\] , if false enter \[0\].

Answer 1

Hint:First, we see the exchange process is.
Hydrogen–deuterium exchange may be a reaction during which a covalently bonded atom is replaced by a deuterium atom. It is often applied most easily to exchangeable protons and deuterons, where such a change occurs within the presence of an appropriate deuterium source, with none catalyst. Hydrogen-deuterium exchange of all non-exchangeable hydrogen atoms during a molecule.

Complete step by step answer:In exchange process, \[{H_2}S\] gas is gone by successive bubbling through ice cold water and boiling water, a liquid containing about \[2\% \] \[{D_2}O\] is obtained which is then concentrated by fractionation and electrolysis. Within the reaction, the hydrogen atoms in \[{H_2}S\] exchange with deuterium from \[{D_2}O\] present in water.

Note: Now we discuss about the distillation process and electrolysis process as below,
Distillation:
The components of a mixture containing two miscible liquids are separated by distillation process. The liquid mixtures are boiled, vaporized, condensed and isolated in this method.
Electrolysis:
The process of decomposing ionic compounds into their elements by passing an immediate current through the compound during a fluid form is called electrolysis.
For example, acidified or salt-containing water is often decomposed by passing current to their original elements hydrogen and oxygen. Molten common salt is often decomposed to sodium and chlorine atoms.
Now we discuss about the factors affecting electrolysis process as,
Factors Affecting Electrolysis:
i) The character of the electrode
ii) Nature and state of the electrolyte
iii) Nature and electrode potential of ions present within the electrolyte and
iv) Overvoltage at the electrodes.
