Stephen Strange performs a titration using Nitric acid (HNO3) to determine the concentration of a sodium hydroxide solution (NaOH) of unknown concentration.
A. Write the neutralization reaction for this experiment and name the salt.
B. Is the pH of the sodium hydroxide solution greater than, less than, or equal to 7? Explain.
C. Phenolphthalein is an indicator that is pink in the presence of the base and is clear in the presence of an acid. if phenolphthalein was added to the sodium hydroxide before the titration, describe what color change you would observe during the titration.
D. If 154 mL of 1.6M HNO3 is needed to titrate 125mL of NaOH, what is the concentration of NaOH?
