Flame Emission Spectroscopy

Cards (12)

  • What is another name for flame emission spectroscopy?
    Flame photometry
  • When metal ions are heated, they emit light with wavelengths specific to the particular metal
  • The flame test can accurately identify metals with similar flame colors.
    False
  • Steps to identify metal ions using flame emission spectroscopy
    1️⃣ Heat the sample
    2️⃣ Light is emitted
    3️⃣ Spectroscope detects wavelengths
    4️⃣ Compare line spectrum to standards
  • Each metal ion produces a unique pattern of wavelengths
  • The intensity of the lines in a line spectrum indicates the concentration of the metal ion.
  • What is the main advantage of flame emission spectroscopy over the flame test?
    Identifies multiple ions
  • When a sample contains multiple metal ions, the line spectrum shows the lines for all of them in a combined pattern
  • Flame emission spectroscopy can be used to calculate the concentration of metal ions in a solution.
  • What are the three main benefits of instrumental methods like flame emission spectroscopy?
    Accurate, sensitive, fast
  • Instrumental methods can detect even tiny amounts of a substance
  • Instrumental methods are often automated to increase speed and efficiency.
