Q: What is the significance of using a control sample in qualitative ion analysis?
Solution:
A control sample serves as a reference for comparison, helping to confirm the presence or absence of specific ions in the test sample.
Steps: 5
Show Steps
Step 1: Understand what a control sample is. A control sample is a known sample that contains specific ions.
Step 2: Know that in qualitative ion analysis, we want to find out which ions are present in a test sample.
Step 3: Use the control sample to compare with the test sample. This helps us see if the same ions are present.
Step 4: If the ions in the test sample match those in the control sample, we can confirm their presence.
Step 5: If the ions do not match, we can conclude that those specific ions are absent in the test sample.
