Chloralkali Industry Quiz

The video tutorial explains the Chloralkali industry, focusing on the electrolysis of brine to produce chlorine, hydrogen gas, and caustic soda. It details the membrane cell process, where brine is used as an electrolyte, and chloride ions are oxidized to form chlorine gas. The membrane allows sodium ions to pass, leading to the formation of caustic soda at the cathode. The tutorial concludes with a brief mention of further topics related to the substances produced.

What year marked the first commercialization of the Chloralkali process?

• 1888

• 1898

• 1908

• 1918

In the membrane cell, what separates the two electrodes?

• An air gap

• A liquid barrier

• A solid wall

• A semi-permeable membrane

What is the role of brine in the Chloralkali process?

• It is a waste product

• It is a byproduct

• It is the electrolyte

• It acts as a catalyst

What happens to chloride ions at the anode during electrolysis?

• They form sodium chloride

• They remain unchanged

• They are oxidized to chlorine gas

• They are reduced to chlorine gas

Which ions pass through the membrane to the cathode half-cell?

• Hydrogen ions

• Hydroxide ions

• Chloride ions

• Sodium ions

What is formed at the cathode during the electrolysis process?

• Nitrogen gas

• Chlorine gas

• Oxygen gas

• Hydrogen gas

What is another name for sodium hydroxide produced in the Chloralkali process?

• Bleaching powder

• Baking soda

• Caustic soda

• Washing soda
