What is the pH of an acetic acid/sodium acetate buffer with [CH3CO2H] = 0.850 M and [CH3CO2-] = 0.550 M? Ka for acetic acid = 1.8×10-5 pH =
For a buffer made from sodium acetate and acetic acid, the Ka of acetic acid is 1.8E-5. What mass of sodium acetate (NaCH3CO2) must be added to 2.50 L of 0.68 M acetic acid to make a buffer solution with pH = 5.75? The answer should be in two significant figures.
What is the pH of a 0.3M acetic acid and 0.3M sodium acetate buffer solution after adding 0.1M NaOH? (Ka = 1.75*10^-5)
a buffer solution of pH =5.30 can be prepared by dissolving acetic acid and sodium acetate in water. How many moles of sodium acetate must be added to 1 L of 0.25 M acetic acid to prepare the buffer? Ka(CH3COOH)=1.8 x 10^-5
You are making a pH 5.0 buffer with acetic acid (pKa = 4.75) and sodium acetate. You want the total concentration of acetate ([acetic acid] + [sodium acetate] ), to be 0.50 M. What concentrations of acetic acid and sodium acetate do you use to make your buffer? acetic acid sodium acetate
2) A buffer solution is prepared by dissolving Sodium Acetate and Acetic acid solutions. If the overall concentration of the solution is 0.2 M and the Ka for acetic acid is 1.74 x 105 (A) What is the buffer ratio? (B) What are the individual concentrations of Acetic acid and sodium acetate needed to prepare the buffer? PH = 5 Can you please write down any assumptions needed for this particular problem? My Professor needs to see thought process. Thank...
calculate the ph of a buffer solution that contains 1.5 M acetic acid (CH3COOH) and 0.3 M sodium acetate (CH3COONa) [Ka=1.8x10-5 for acetic acid]
3.) A buffer containing acetic acid and sodium acetate has a pH of 5.25. The Ka value for CH3CO2H is 1.80 × 10-5. What is the ratio of the concentration of CH3CO2H to CH3CO2-?
Calculate the grams of sodium acetate required to make 250.0 mL of a pH 5.50 buffer solution using 0.100 M acetic acid (Ka of 1.8x10-5).
