Chlorien gas is manufactured by oxidizing hydrogen chloride gas with oxygen in the presence of cypric chloride (catalyst) heated to`400^(@)`. This process is known as:

Options

A. Deacon's process
B. Weldon's process
C. Downs process
D. Mond's process

Answer

1

Explanation

`4HCI+O_(2)rarr overset(CuCl_(2))underset(400^(@))rarr2Cl_(2)+2H_(2)O`
The catalytic action of cupric chloride can be explained as follows:
`2CuCl_(2)overset(Delta)rarrCu_(2)Cl_(2)+Cl_(2)`
`2Cu_(2)Cl_(2)+O_(2)("air")rarr underset("Copper oxychloride")(2Cu_(2)OCl_(2))`
`Cu_(2)OCl_(2)+2HCI rarr 2CuCI_(2)+H_(2)O`
Welcdon's process involves the heating of pyrolusite mineral `(MnO_(2))` with concentrated hydrochloric acid:
`MnO_(2)+4HCI rarr MnCI_(2)+2H_(2)O+CI_(2)`
In DOwes porcess ,chlorine is produced by the electrolysis of fused `NaCl`
Both `Cl_(2)` and `NaOH`are produced commercilally by the electrolysis of brine.
