I can't figure this problem out. Please help! Chloroacetic acid, HC2H202CI, is a stronger monoprotic acid than acetic acid. In a 0.10 M solution, the pH is 1.96. Incorrect. Did you use the correct equilibrium expression? Did you use the correct number of significant figures? Calculate the Ka for chloroacetic acid 0.0013 Ka
The pKa of chloroacetic acid is 2.9. If an organic chemist has a 0.10 M aqueous solution of chloroacetic acid at pH 2.4, what percentage of molecules/ions will be in the basic form?
The pH of a 0.115 M solution of the weak acid, chloroacetic acid (chemical formula ClCH2COOH), is measured to be 1.92 at equilibrium. Calculate the Ka of this monoprotic acid.
Solution A is a 1.00 L buffer solution that is 1.196 M in acetic acid and 1.196 M in sodium acetate. Acetic acid has a pKa of 4.74. What is the pH change of this solution upon addition of 0.1 mol of HCl? Enter your answer numerically to three significant figures.
Lactic acid is a simple organic acid that is somewhat stronger than acetic acid. The lactate ion is the conjugate base of lactic acid and is one product of animal (including human) metabolism. Ka for lactic acid is 1.38 x 10-4. If the resting amount of lactate in blood is 2.0 mM and typical blood pH is 7.40, what is the lactic acid concentration in blood? Calculate the pH of a 0.0100 M solution of lactic acid. Calculate the pH...
2. A 0.10 M solution of lactic acid, a weak monoprotic acid of to have a pH of 2.43. What is the value of Ka for the acid and the %
What concentrations of acetic acid (pKa 4.76) and acetate would be required to prepare a 0.10 M buffer solution at pH 4.5? Note that the concentration and/or pH value may differ from that in the first question. STRATEGY 1. Rearrange the Henderson-Hasselbalch equation to solve for the ratio of base (acetate) to acid (acetic 2. Use the mole fraction of acetate to calculate the concentration of acetate. 3. Calculate the concentration of acetic acid Step 1: Rearrange the Henderson Hasselbalch...
The pH of a 4.39×10-3 M solution of a weak monoprotic acid is 4.40. Calculate Ka for this monoprotic acid to three significant figures.
Question 6 (2 points) Chloroacetic acid, HC2H2CIO2, has a greater acid strength than acetic acid, because the electronegativity chlorine atom pulls eloectroms way from the O-H bond and thus weakens it. What is the pH of a 0.043 M aqueous solution of chloroacetic acid? The Ka for HF is 1.3x10-3. You must solve the quadric equation for this problem. Express your answer to two decimal places. Your Answer: Answer s7 Question 7 (2 points) What is the pH of a...
