4. Data Analysis (Known Samples)
Analyze your data on the previous page. To help you identify if the cation or anion is
responsible for the colors observed during a flame test, answer the questions below:
i. The flame tests for sodium sulfate and sodium chloride produced similar flame test
colors. What general flame color was observed?
ii. Which ion (cation or anion) remained the same between sodium sulfate and
sodium chloride?
