QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Industrial Processes for Sodium Hydroxide and Chlorine.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe one advantage of the membrane cell process over the mercury cell process.
Describe the environmental impact of the diaphragm cell process.
Describe the main difference between the mercury cell and membrane cell processes.
Explain why brine is purified before use in the chlor-alkali process.
Explain why it is important to keep chlorine and sodium hydroxide separated during the industrial process.
Explain why the production of sodium hydroxide and chlorine is considered an example of a redox reaction.
Explain why the purity of sodium hydroxide is higher in the membrane cell process than in the diaphragm cell process.
In the diaphragm cell process, what is the main purpose of the diaphragm?
During the electrolysis of brine, which ion migrates towards the cathode? (1) Sodium ion (2) Chloride ion (3) Hydroxide ion (4) Hydrogen ion
In the membrane cell process, what is the function of the membrane? (1) To allow only sodium ions to pass (2) To allow only chloride ions to pass (3) To allow both sodium and chloride ions to pass (4) To prevent any ions from passing
What is the main raw material used in the industrial production of sodium hydroxide and chlorine? (1) Sodium chloride (2) Potassium chloride (3) Calcium chloride (4) Magnesium chloride
Which of the following is a disadvantage of the diaphragm cell process? (1) High cost (2) Use of toxic mercury (3) Dilute sodium hydroxide produced (4) High purity of products

Fill in the blank: The membrane in the membrane cell process is usually made of ________.
Fill in the blank: The overall reaction for the chlor-alkali process is 2NaCl + 2H2O → 2NaOH + ________ + H2.
True or False: Hydrogen gas is a by-product in all three main industrial processes for sodium hydroxide and chlorine production.
True or False: The diaphragm in the diaphragm cell is permeable to both cations and anions.
True or False: The main products of the chlor-alkali process are sodium hydroxide, chlorine, and hydrogen.
True or False: The membrane cell process produces a more concentrated sodium hydroxide solution than the diaphragm cell process.
