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 =
To have solutions of HCl and acetic acid (CH3CO2H) with the same pH, which of the following needs to be done? The concentration of each solution needs to be the same. The concentration of HCl needs to be higher. The concentration of acetic acid needs to be higher. The solutions can never have the same pH. Volume of acetic acid solution must be lower.
Estimate the temperature at which a reaction will be at equilibrium, given these values Delta H = -10 kJ, Delta S = -25 J/K. (4)
Determine Ka for a 0.10M acetic acid (CH3CO2H) solution that has a pH of 2.87.
In the gas phase, acetic acid exists as an equilibrium of monomer and dimer molecules. (The dimer consists of two molecules linked through hydrogen bonds.) The equilibrium constant, Kc , at 25 °C for the monomer-dimer equilibrium 2CH3CO2H↔(CH3CO2H)2 has been determined to be 3.2x104. Assume that acetic acid is present initially at a concentration of 8.3x10-4 mol/L at 25 °C and that no dimer is present initially. a.) What percentage of the acetic acid is converted to dimer Percentage =...
