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...
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!
Please explain
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...
a titration curve of an unknown acid whose equivalence point is at pH 7 segguest that? a) this is a weak acid because the equivalence point of all strong acids is below 7 b) this is a strong acid because the equivalence point of all strong acids is pH 7 c) this is a weak acid because the equivalence point of all weak acids is pH 7 d) this is actually pure water please explain as much as you can. i think...
1) What is the difference between endpoint and equivalence point in a titration? Why is it important to know the difference when analyzing your results? Unknown HCl 1: Trial # 1 Vol HCI (ml) Initial % Error (NaOHT (mol/L) Volfinal- Volinitial = (mL) Total Volume NaOH (ml) 10.00 10.00 10.00 10.00 0.098 0.098 0.098 0.098 Volume NaOH (mL) 5.52 10.29 15.21 22.20 Volume NaOH (mL) 0.00 5.52 10.29 15.21 3 L Average: Unknown HCl 2: Trial # 1 Vol HCI...
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
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.
Is the pH at the equivalence point in the titration of 0.10 M C2HSNH2 with 0.10 M HCI acidic, basic, or neutral? Explain your answer.
A) What is the pH at the equivalence point in the titration of a 24.3 mL sample of a 0.333 M aqueous hydrofluoric acid solution with a 0.425 M aqueous barium hydroxide solution? pH = B) How many grams of solid sodium hypochlorite should be added to 1.00 L of a 0.206 M hypochlorous acid solution to prepare a buffer with a pH of 8.373 grams sodium hypochlorite = g. C) How many grams of solid potassium fluoride should be...
