The concentration of the adsorption indicator used in titrations should be:
Equal to the concentration of the adsorbate
Higher than the concentration of the adsorbate
Lower than the concentration of the adsorbate
Irrelevant to the endpoint detection
The concentration of the adsorption indicator should be lower than the concentration of the adsorbate to avoid affecting the overall adsorption process.
