Why should soapy hands be rinsed under running water and not in a basin?

  1. Soap does not dissolve in a basin
  2. Basin water can bring germs back to hands
  3. Running water is always much warmer
  4. Basin water makes the hands too dry
Show answer and solution

Correct answer: B. Basin water can bring germs back to hands

Water standing in a basin can carry germs, so rinsing there can put them back on clean hands.
