- 3. Choi is fond of carbonated beverages so he crafted his own soda formulation called "Sodalicious." Ulan, who is a fellow enthusiast, also made her own formulation which she called "Soda Pop!" to challenge his friend Choi. To know which formulation is better, they sought to determine the carbonic acid content of their soda formulations using titration. In the first part of their experiment, a 0.5 Mlabeled NaOH solution was standardized against 0.350 grams of KHP (MW = 204.22 g/mol) primary standard that is 99.6% pure. The titration required 3.16 mL of the NaOH solution to reach the phenolphthalein endpoint. In the second part of their experiment, Choi and Ulan independently prepared their samples by taking 25.0-mL of their soda sample and diluting it to 30.0 mL. Using the same titrant and indicator, Choi's "Sodalicious" required 1.39 mL of the standardized titrant to reach the endpoint, while Ulan's "Soda Pop!" required 0.926 mL of the same titrant to reach the endpoint.
