Plot a graph of oxygen produced (number of bubbles) against the distance from the tube, remembering that the independent variable goes on the x-axis. When little or no carbon dioxide is present, BTB will show a blue color. This depletion of carbon dioxide can be visualised using hydrogen carbonate, an indicator which changes colour depending on the carbon dioxide present. Water that has a pH >8.3 is said to have "phenolphthalein alkalinity," which is alkalinity due primarily to the presence of carbonate or hydroxide ions. Phenolphthalein is a good indicator for the first reaction because it responds to the pH change caused by the formation of sodium hydrogencarbonate. what plants can be used to investigate photosynthesis? Wouldn't it be better to simply make your own? The most common salt of the bicarbonate ion is sodium bicarbonate, NaHCO3, which is commonly known as baking soda.
