• Titration calculations: • A chemist titrates 30.00 mL of 0.200 M acetic acid with 0.100 M sodium hydroxide. Calculate the pH at the four titration points described below. • If needed, use k, = 1.7x10-5 for acetic acid. 1. Before any sodium hydroxide is added. 2. After adding 25.00 mL of sodium hydroxide. 3. After adding 60.00 mL of sodium hydroxide. 4. After adding 75.00 mL of sodium hydroxide.
Consider the titration of 100.0 mL of 0.200M acetic acid (CH3COOH, Ka=1.8 x10-5) by 0.100M KOH. Calculate the pH of the resulting solution after 50.0 mL 0.100M KOH is added.
I’m confused on how to do the question. Please help Lecture 15 At-home Practice Buffer conceptual and calculation: A chemist needs a pH 3.90 buffer. Make the best choice from these four acids to start making a buffer nearest the desired pH. * Hydrofluoric acid, HF Ka-6.8x104 . Formic acid, НСНО, K,-1.7x10-4 Propionic acid, HC,HO2 K, 1.3x105 Acetic acid, HCH,CO2 K, 1.7x10 Assume the best acid is combined with its appropriate conjugate base.

1.Draw the pH titration curve for the titration of 35 mL of 0.150 M acetic acid with 0.200 M NaOH. Include the pH values and NaOH volume requested below on your pH titration curve. Also, put on the curve the species that dictates the pH at the requested pH values. For acetic acid, K = 1.8 x 10%. 1) the initial pH 2) the pH after 15.0 mL of NaOH have been added 3) the volume of NaOH at the...
ACIDS AND BASES Calculating the pH at equivalence of a titration A chemist titrates 200.0 mL of a 0.5694 M sodium hydroxide (NaOH) solution with 0.6230 M HCl solution at 25 °C. Calculate the pH at equivalence. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HCl solution added. PH-0 5 ?
