HCl gradually reduces the alkalinity of the solution until the pH is 7. Photosynthesis is the process by which plants, and some other organisms, produce their own energy source, making them autotrophs or producers rather than heterotrophs or consumers, which gather energy by consuming other animals. what plants can be used to investigate photosynthesis? NaHCO 3 (aq) + HCl (aq) NaCl (aq) + CO 2 (g) + H 2 O (l) Phenolphthalein is a good indicator for the first reaction because it responds to the pH change caused by the formation of sodium hydrogencarbonate. However, an increase in carbon dioxide changes the indicator to yellow and a decrease in carbon dioxide changes it to purple. That point of equilibrium is basically a limit, or a ceiling. Teaching NGSS is more than checking off standards. Turn the delivery knob to eject air and a few drops of titrant. When conducting an experiment, it is important to remember how to design an experiment properly.
