Q

What are the observations in a reaction between potassium and cold water (8)

A
  1. Lilac flame produced
  2. Potassium melts into a tiny ball
  3. Potassium floats and spins on the surface of the water (most vigorously)
  4. Effervescence/fizzing
  5. Heat released (seen through steam)
  6. Potassium disappears quickly
  7. Colourless solution produced
  8. Crackles at the end/ chance to produce a small explosion

Q

What are the observations in a reaction between sodium and cold water (6/7)

A
  1. Sodium melts into a tiny ball
  2. Sodium floats and spins on water surface (slightly less vigorously than potassium)
  3. Effervescence/fizzing
  4. Heat released (seen through steam)
  5. Disappears at the end
  6. Colourless solution formed
    +7. Chance to ignite with an orange flame (depends on volume of metal)
