Other questions in this quiz

2. How do you test for halide ions?

  • Fizzes in hydrochloric acid
  • Add bromine water and it will go clear
  • Add dilute nitric acid and then silver nitrate solution and see what colour the precipitate is
  • Flame test

3. What is the molecular ion peak?

  • Shows the relative molecular mass of a substance where the individual compound with a large peak corresponds to an ion with one electron removed
  • Describes the reactivity of that compound
  • Shows the atomic number in a compound
  • Shows the atomic number of one of the elements

4. How does a mass spectrometer work?

  • Matches the compounds against the mass spectra of known substances
