From Wikipedia, the free encyclopedia A hydrogencarbonate indicator (hydrogencarbonate indicator) is a type of pH indicator that is sensitive enough to show a color change as the concentration of carbon dioxide gas in an aqueous solution increases. The simplest way to collect carbon dioxide is to react calcium carbonate (or limestone chips) with hydrochloric acid. Water and carbon dioxide combine to form carbonic acid (H 2 CO 3 ), a weak acid that breaks (or "dissociates") into hydrogen ions (H +) and bicarbonate ions (HCO 3- ). What color is hydrogen carbonate indicator solution. However, an increase in carbon dioxide changes the indicator to yellow and a decrease in carbon dioxide changes it to purple. How does a hydrogen carbonate indicator work? One of the easiest practicals to investigate photosynthesis and the effect of varying limiting factors on the rate of photosynthesis is using Cabomba or Elodea plants, more commonly known as pondweed, within a boiling water tube.
