The traffic light reaction experiment

The traffic light reaction experiment is a chemical experiment that demonstrates the oxidation-reduction reaction between compounds. In this experiment, the color of the traffic light can be observed to understand the electron transfer and oxidation-reduction reactions between compounds. One of the most common traffic light response experiments is the bingo snow light experiment.

Substances required for the experiment:

Bingo dauber:

It contains substances of various colors.

Acidic and basic solutions:

Each solution consists of budding hydrochloric acid (HCl) and sodium budding (NaOH) diluted with water.

Paper towels or extra paper:

This is the paper that will be used to wipe off any moisture that occurs during the experiment or to be used in the experiment.

Experimental Procedure:

Draw on bingo canvas:

Draw each color on a bingo snow paper paper. As a rule, red, yellow, and blue are used.

To draw the color of the test subject:

Draw the color of the test object corresponding to each color on the drawing paper.

Observe the color change:

Drop a basic solution (sodium) into the area corresponding to each color and an acidic solution (hydrochloric acid) on the other part.

Carefully observe the changing colors.

Results:

Red:

Bingo Snow When you drop a bingo snow on the drawing paper, it turns from red to yellow.

This refers to an oxidation-reduction reaction in which the basic solution (sodium) changes the color of the bingo.

Yellow:

When you drop a bingo snowflake on the drawing paper, it will turn from yellow to green.

This refers to an oxidation-reduction reaction in which the basic solution (sodium) changes the color of the bingo.

Blue:

When you drop a bingo snowflake on the drawing paper, it will turn from blue to red.

This refers to an oxidation-reduction reaction in which an acidic solution (hydrochloric acid) changes the color of the bingo.

Experiment Description:

In this experiment, an acid-base neutralization reaction occurs. The compounds contained in bingo snow are pH sensitive and exhibit a variety of colors depending on the electron transfer of basic and acidic solutions. This helps learners understand the importance of oxidation-reduction reactions and pH. Testing must be conducted under strict supervision and supervision while complying with safety regulations.
