Question: In qualitative analysis, what does the presence of a white precipitate indicate when testing for chloride ions?

Options:

  1. Presence of sulfate ions
  2. Presence of phosphate ions
  3. Presence of chloride ions
  4. Presence of nitrate ions

Correct Answer: Presence of chloride ions

Solution:

A white precipitate formed when adding silver nitrate to a solution indicates the presence of chloride ions.

Questions & Step-by-Step Solutions

In qualitative analysis, what does the presence of a white precipitate indicate when testing for chloride ions?
  • Step 1: Understand that we are testing for chloride ions in a solution.
  • Step 2: Add silver nitrate solution to the sample you are testing.
  • Step 3: Observe the reaction that occurs after adding silver nitrate.
  • Step 4: Look for a white precipitate that forms in the solution.
  • Step 5: If a white precipitate appears, it indicates that chloride ions are present in the solution.
  • Qualitative Analysis – The process of determining the presence of specific ions or compounds in a solution based on observable reactions.
  • Precipitation Reaction – A chemical reaction where two soluble salts react to form an insoluble salt, which appears as a precipitate.
  • Chloride Ion Testing – The use of silver nitrate to test for chloride ions, which results in a white precipitate of silver chloride.
