QuestionSection I: Purpose (List 1 – 3 goals for this experiment.Why did… Section I: Purpose (List 1 – 3 goals for this experiment.?hy did you do this experiment?)Section II: Theory (Answer the following theory questions related to the experiment)1.??Define acids and bases.2.??Define pH and the pH scale and how it relates to classifying a substance as acid, base, or neutral.3.??Define molarity.4.??What is the balanced chemical equation for the reaction is this titration experiment?1.???Read sections 12.4, 12.5, 14.7 and 14.8 of your lecture textbook for background information. 2.???Watch the following videos: https://www.youtube.com/watch?v=HVjvFydMOc8??https://www.youtube.com/watch?v=VADhF7M8bJ8*The videos involve the same general method: a solution of HCl acid is titrated with a solution of NaOH base using phenolphthalein as an indicator.?he first ?of the first video shows an example titration experiment, while the second ?of the first video shows a useful titration calculation method using the dilution equation (C1V1 = C2V2).The second video shows a procedure that follows more what would be done in an in-person lab on campus.?aOH (aq) + HCl (aq) ======= NaCl (aq) + H2O (l)????????????????????????????????1.) How would the calculated concentration of the HCl be affected, if the sodium hydroxide were poured from a beaker that contained some water before the NaOH were added to it??2.) What color is phenolphthalein in acid? What color is it in base??3.) The acid and base in this experiment are completely harmless?rue or False? Explain your answer.?4.) What color did you see at the end-point of the titration when using phenolphthalein???.) What volume of 0.200 M sodium hydroxide is required to completely neutralize 50.00 mL of 0.199M hydrochloric acid? Section III: Procedure (Briefly outline the steps you followed in order to complete the experiment) Section IV: Discussion and Conclusions (Answer the following questions) Comment on the precision of the concentration determined by the trials.?hint: the closeness of the trial results to each other is a good indication of the precision)ScienceChemistryCHEM 110
