Question: In a qualitative analysis using paper chromatography, which factor primarily affects the separation of ions?

Options:

  1. Temperature
  2. Solvent polarity
  3. pH of the solution
  4. Ion concentration

Correct Answer: Solvent polarity

Solution: 

The solvent polarity is the primary factor affecting the separation of ions in paper chromatography, as it influences the interaction between the stationary phase and the ions.

Questions & Step-by-Step Solutions

In a qualitative analysis using paper chromatography, which factor primarily affects the separation of ions?
  • Step 1: Understand what paper chromatography is. It is a method used to separate different substances in a mixture.
  • Step 2: Identify the two phases in chromatography: the stationary phase (the paper) and the mobile phase (the solvent).
  • Step 3: Recognize that the solvent is a liquid that moves through the paper and carries the ions with it.
  • Step 4: Learn about polarity. Polarity refers to how molecules interact with each other based on their electrical charge.
  • Step 5: Realize that different ions have different polarities, which affects how they interact with the solvent and the paper.
  • Step 6: Conclude that the polarity of the solvent is the main factor that affects how well the ions separate on the paper.
  • Solvent Polarity – The degree to which a solvent can dissolve ionic or polar substances, affecting their movement on the chromatography medium.
  • Stationary Phase Interaction – The relationship between the ions and the paper (stationary phase) that influences how far the ions travel during chromatography.
  • Ion Separation – The process of distinguishing different ions based on their movement through the stationary phase under the influence of the solvent.
