Students Mola and Rity were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL diluted sample contains 0.21 mmol of lactic acid. MW: Lactic Acid (90.08) a.

Consider an analyte solution of 50.0mL of 0.050M hydrochloric acid, HCl, titrated against 0.10 M sodium hydroxide, NaOH (the titration you will be performing in the lab!). (a) What is the chemical equation representing the titration reaction? (b) At the start of the titration, before any NaOH is added, what ions or molecules are present in the solution? You only need to list chemical species that are present in appreciable quantities - anything that is considered a small enough concentration to where you’d make a small-change approximation on an ICE table doesn’t need to be included. (c) Which of species you identified in part (b) will determine the pH of the solution?
