Q: Which qualitative analysis technique is most effective for detecting trace metals in a sample?

Solution: Atomic absorption spectroscopy is highly effective for detecting trace metals due to its sensitivity and specificity.

Steps: 6

Step 1: Understand what trace metals are. They are metals present in very small amounts in a sample.
Step 2: Learn about qualitative analysis techniques. These are methods used to identify the presence of substances in a sample.
Step 3: Identify the techniques used for detecting metals. Common techniques include atomic absorption spectroscopy, inductively coupled plasma, and others.
Step 4: Focus on atomic absorption spectroscopy (AAS). This technique uses light to measure how much of a metal is in a sample.
Step 5: Recognize the advantages of AAS. It is very sensitive, meaning it can detect very low concentrations of metals, and specific, meaning it can identify different metals accurately.
Step 6: Conclude that atomic absorption spectroscopy is the most effective technique for detecting trace metals due to its high sensitivity and specificity.
