Introduetion Acld-base terations involvo the neutraltration resction between the hydrenilum and hyufrovide forn. Theee lone combine to form the nevilrat water molecule. H2Oam++OHion+2H2O The equilvalence polnt is achieved when equal amounte of hydronium and hydroxide ions are present within the titration flesk. As the equivalence point is reached. there is a rapid charve in. pH and can be recognized by a chemical lindicatof. In this oxperiment, you will tarain a sample of vinegar against a sodium hydroxide solution of known concentration. Pre-lab Questions (reforence: text pages 394-399: youtube: "Titration Tochniques Using a Buret") 1. In this lab, you will perform a titration using sodium hydroxide and acetic acid (Virvogar). Write the balanced neutralization reaction that oecurs betwosn sodium hydroxide and acetic acid. 2. What specialized oquipment is neoded to perform a titration? 3. Consider the sodium hydroxide reactant. a) Is the concentration of the sodium hydroxide known or unknown? b) Is sodium hydroxide the analyte or the titrant? 4. Consider the acetic acid reactant. a. What type of flask is the acetic acid placed in? b. What volume of acetic acid is used? c. Is the acetic acid the analyte or the titrant? 5. You will add sodium hydroxide to the acetic acid until all the acetic acid is consumed. This is a special point in the titration called the point. 6. An indicator solution is used to indicate when all the acetic acid has been consumed and that the reaction is complete. a. What is the name of the indicator solution? b. Is this indicator mixed with sodium hydroxide or acetic acid? c. How exactly does the indicator let you know when the reaction is complete
