6. Titration is routine, useful laboratory technique that can be used to confirm the concentration of a particular reagent. Forexample, you used an acid-base titration to determine the strength of a common household product – vinegar.a. Before performing a titration of vinegar itself, you first had to standardize the solution used to analyze vinegar.i) State the identity of solution used to analyze vinegar (name the compound) and explain why the solutionhad to be standardized.ii) State the name (an abbreviation is fine) of the compound used standardize the test solution and explainwhy that compound was selected for use in standardization.iii) State the key mathematical result or goal of the standardization you performed.b. The completion of the acid-base titration was recognized by the use of an indicator.i) Define the term indicator.ii) Name the indicator used in the acid-base titration and state the color changed that that particularindicator undergoes.c. The visual indication that a titration is complete is known as the endpoint of the titration.i) The endpoint of a titration is related to the equivalence point of a titration. Define the term equivalencepoint and explain why the endpoint and equivalence point of a titration are not the same.ii) Explain the mathematical significance of the equivalence point. As part of your answer, write the keyequation that is true at the end of the titration of vinegar with the analysis solution.

a.) i.) As vinegar contains Acetic acid , so for titration of an acid , we need a base. ii) As most base solutions are secondary standardized, so we need to standardise base solutions with a primary standard acid solution . iii) From the standardization of base solution, we get to know the concentration ( Molarity ) of base solution , so that we can calculate concentration of Acetic acid in vineger when we would titrate that base with vinegar. On the basis to above discussion , we have : a.) i) To analyze vinegar , we mainly use base solution : NaOH ( sodium hydroxide ) solution . This NaOH solution needs to be standardize before the actual titration because NaOH solution is a secondary standardized solution. ( Secondary standardized solution are those solutions whose concentration can not be determined accurately from their amounts used in making their solution. Their concentration has to be calculated by titrating them a primary standard solution . ) ii) The compound mainly used for standardization of NaOH solution is Oxalic acid ( C2H2O2 ) Solution . This oxalic acid solution is used in standardization of NaOH because Solution of oxalic acid is a primary standard solution . iii) On performing standardization of NaOH solution with oxalic acid solution, we would get the actual concentration of NaOH solution . ( So after knowing actual concentration of NaOH solution , we can titrate Vinegar with it and can calculate concentration of acetic acid in vineger ) .

13. A chemistry student offers a possible improvement to this lab. Since one goal of this lab is to determine the mass of the precipitate produced, wouldn't it be possible to measure the mass of an empty beaker, mix the solutions, and boil off the water until it is entirely evaporated, leaving only solid behind? Then the beaker with the precipitate could be weighed, and the difference between this mass and that of the empty beaker would be the mass of the precipitate. This would eliminate the need for the filtration step. Explain why this is a poor suggestion. Remember to check your reasoning on this question and all other questions with your instructor.
