Magical Color Change

Magical Color Change 1

Magical color change is a fun science experiment for kids to do at home which shows how different solutions give different colors, on addition of another single color. How is this possible that the same color will give different colors? You can easily unlock this mystery of colors by doing this cool science experiment.

What to Do!

  1. Place the color palette above the activity sheet so that the grooves of palette and boxes in the activity sheet matches with each other.
  2. Now, arrange the test-tube in the order of base 1, base 2, neutral, acid 1, acid 2 and acid 3.
  3. Place the indicator test-tube aside the color palette.
  4. Place a pipette aside every test-tube.
  5. Put the solutions in the grooves in the order of base 1, neutral and acid 1, base 2, neutral and acid 2, base 2, neutral and acid 3,
  6. Now, put few drops of indicator in each groove one-by-one.
  7. You can see how magical colors appear slowly in each groove.
  8. Now, fill the boxes in activity sheet with the same color as you see in the grooves.

Working Principle of Magical Color Change :

In this experiment when we arrange acids, neutrals and bases in the color palette and add drops of indicator in it, we can observe that all the acids turn orange, neutrals turn yellow and bases turn pink. This is because we are using Phenol-red as the other solution, which is a pH indicator and it exhibits a gradual transition in color from orange (in acidic solution, pH range below 6) to yellow (in neutral solution, pH range between 6-8) to bright pink or fuchsia (in basic solution, pH range above 8). This color change helps us to detect acids, bases and neutral solutions. If we pour a few drops of this indicator in an unknown liquid, we can find out if it is acidic, basic or neutral from its color change. Phenol-red is even used in swimming pools to test the chlorine content of water in the pool!
