In a titration, why does it generally require less titrant to reach the first equivalence point from the beginning, compared to reaching the second equivalence point from the first equivalence point? Explain the underlying mechanism why.

In a titration that initially contains carbonate and bicarbonate, the volume of titrant required to reach the first equivalence point is less than that required to titrate from the first equivalence point to the second. Explain Why?
Please Explain in detail. Thanks h a titration that Initiatly Contains Carbonats and bicarbonat&, Of titrant required to reach tee tre volum tirst equivalence Point is Less than that require dl to titrate from the first equivalence point to the Serond Explain why?
7. If the second equivalence point in the titration of a diprotic acid is at 39.48 mL of strong base titrant added, at what volume is the? robudno b First half-equivalence point? Second half-equivalence point? iniog solving First equivalence point? Second equivalence point? 39.48 mL
3. Explain why the pH at the equivalence point of the titration of vinegar with sodium hydroxide is greater than 7.00 while the equivalence point of the titration of Hydrochloric acid with sodium hydroxide is 7.00.
Equivalence Point for Titration #1: 24.96 mL Equivalence Point for Titration #2: 25.40 mL Equivalence Point for Titration #3: 25.20 mL Midpoint pH for Titration #3: 9.80 QUESTIONS: 4) Set up the calculation required to determine the concentration of the NaOH solution via titration of a given amount of KHP. Include all numbers except the given mass of KHP. 5) Set up the calculation required to determine the concentration of the unknown strong acid via titration with a known volume...
The pH at the equivalence point of a titration of an unknown monoprotic substance with a strong titrant is determined to be 6.63. Based on this pH value, explain whether the unknown substance is a strong acid, strong base, weak acid, or weak base. A chemist wants to perform a reaction at pH = 8.3 so they attempt to make a buffered solution. For this buffer, the chemist dissolves 12.5 moles of methylammonium, CH3NH3+, (Ka = 2.3 x 10–11) and...
1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...
Part A The volume required to reach the equivalence point of an acid-base litration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. It does not, however, depend on the whether or not the acid or base being litrated is strong or weak. Explain Match the words in the left column to the appropriate blanks in the sentences on the right...
Titration of 25.00 mL of 0.100 M HCl with 0.100 M NaOH (strong acid, strong base): Answer the following questions: 4. Calculate the initial pH 5 Why is pH = 7 at the equivalence point? 6Why does the pH rise slowly at first, very rapidly near the equivalence point, and slowly after the equivalence point? 7. Why does it require 25.00 mL of NaOH to reach the equivalence point?
Using the equivalence point volumes determined from the expanded titration graph or the first derivative graph, the volume of acetic acid titrated (pipet volume), and the concentration of your diluted NaOH standard solution, calculate the concentration of the unknown acid solution. Equivalence point volume= 18.5 Concentration of diluted NaOH= 0.19709 Volume acetic acid= 5 mL (diluted in 70 mL dH20 but I guess it does not matter?)
