12.00 mL of lemon juice containing citric acid is placed into an Erlenmeyer flask to which 2 drops of phenolphthalein indicator are added. Sodium Hydroxide (0.880 M) is delivered from a buret and reacts with the citric acid in an acid/base neutralization reaction. After 23.00 mL of NaOH has been delivered, the solution in the flask changes to a light red color. This signifies the endpoint of the reaction. Calculate, M, citric acid. Report your answer to two significant figures. Do not round any answers until the end of your calculation. Do not include your unit, M, with the answer. Type only the numerical answer.
