Question

which type of chemical process is used to remove salt from ocean water?
a) desalination
b) alkylation
c) doping
d) dehydrogenation

Explanation:

• Option A: Desalination is the process of removing salt (and other impurities) from saline water like ocean water to make it suitable for human use (drinking, irrigation, etc.).
• Option B: Alkylation is a chemical reaction that involves adding an alkyl group to a molecule, and it's not related to removing salt from water.
• Option C: Doping is a process used in semiconductors (adding impurities to change electrical properties) or in sports (using banned substances), not for desalting water.
• Option D: Dehydrogenation is a reaction that removes hydrogen from a compound, which has nothing to do with removing salt from ocean water.

Answer:

A) Desalination
