What is the difference between the equivalence point of a titration and the end point of a titration? They are not different. The equivalence point is when the reaction has reached completion while the end point is an estimate of the completion. The equivalence point is when the reaction has reached completion while the end point is the half-way point of the titration. The equivalence point allows us to calculate unknown quantities of reactants while the end point does not.
1) A student overshot the end point of their titration, resulting in a dark pink solution rather than the faint pink color recommended by the procedure. How would this affect the student's experimentally determined value of NaOH molarity? Explain.
Determine the pH at the equivalence (stoichiometric) point in the titration of 48 mL of 0.28 M CH3NH2(aq) with 0.2 M HCl(aq). The Kb of methylamineis 3.6 x 10-4. The answer is 5.74. Please explain!
Understand how to complete titration calculations Question The end point in a titration of a 25.5 mL sample of aqueous HCI was reached by the addition of 5.6 mL of 2.5 M NaOH titrant. The reaction proceeds by the following equation. HCl(aq) + NaOH(aq) + NaCl(aq) + H2O(1) What is the molar concentration of HCl? • Report your answer with two significant figures.

10 Titration 1 point Based on this titration, what is the pH of the solution at its pka? Titration Type your answer... 11 1 point Identify the spot below where the amount of acid is equal to the amount of base. pH Titration 10 15 20 Volume of titrant (ml) 25 30 pH 5 25 30 10 15 20 Volume of titrant (ml)
compare and contrast the colorimetric determination of a titration equivalence point using an acid-base indicator versus electrochemical determination of a titration equivalence point using a pH meter. please explain pros and cons of both methods
