The initial addition of sodium hydroxide solution is not enough to neutralize the acid present, and the indicators remain colorless. Because the contents of the beakers are acidic, the indicators are colorless. The indicator solutions used are very concentrated, more concentrated than standard indicator solutions, producing intense solution colors.Īt the start, each beaker contains one of the six rainbow color indicator solutions along with the acid/alcohol mixture. Because these colors are close to the three primary colors, virtually any color of the rainbow can be produced by some combination of these indicators in basic solution. The three indicators used are all colorless in acidic solution, but each produces a different color in basic solution. This demonstration shows that a mixture of indicators can produce a color change different from that obtained with the individual indicators, resulting in the colors of the rainbow appearing and disappearing. The colored solution beakers are then mixed in a large container resulting in the colors disappearing once again.Ī number of objectives are satisfied with this presentation, including a) demonstrating color changes of solutions due to changes in pH of the solutions, b) demonstrating the reversibility of indicator color changes, c) providing an introduction to acid/base chemistry, d) getting students to think about how acids and bases interact, and e) providing an introduction to standard indicators. The colors disappear and reappear when other colorless liquids are added to the beakers. Red, Orange, Yellow, Blue, Indigo, Violet, and Green.When a colorless liquid is poured into six beakers, the liquid in each beaker turns a different color of the rainbow.
