1.) Calculate the molarities of the buffer species: You have 170.0 mL of an acetic acid and conjugate base buffer. The total moles of the buffer equals 0.100M, the pH is 5.00. The ka(acetic acid) is 1.8 x 10 -5. Show the buffer equilibrium rxn; show all calcs and steps for credit. 2.) How would you make a buffer given the following: A bottle of solid sodium acetate, a stock bottle of 6.0M acetic acid, water and lab equipment is...
*2.4 Consider a 1M water-solution of acetic acid. a) Given the dissociation constant of acetic acid, K=1.75*10--M, calculate the concentration of non-dissociated acetic acid at equilibrium. Hint The dissociation process is described as a first order process relative to each of the components: CH3COOH CH3COO- + H+
1.0 mol of ethanol and 1.0 mol of acetic acid are dissolved in water and kept at 100? degrees C. The volume of the solution is 250 mL. At equilibrium, 0.25 mol of acetic acid has been consumed in producing ethyl acetate. Calculate Kc? at 100 degrees C for the reaction: C2H5OH?(aq) + CH3CO2H(aq) CH3CO2C2H5(aq) + H2O?(l)
11. (5 pts) Calculate the molarity of 60.05 g of acetic acid, HC2H302, dissolved in water to make 0.250 L of solution. (Atomic weights: H = 1.008, C = 12.01, 0 = 16.00).
Acetic acid (CH3COOH) dissociates in water with an equilibrium constant of 1.8x10^-5. Calculate the equilibrium concentrations of all the compounds involved in that process if 2.0M CH3COOH is initially mixed with 1.0M CH3COOH and 1.0M H3O, then allowed to reach equilibrium. Also, determine the pH and pOH of the solution.
colligative properties: freezing point depression. Gen chem 2 HINKI Acetic acid is known as a weak acid (electrolyte) when it is dissolved in water. A solution was prepared by dissolving acetic acid in cyclohexane to yield a concentration of 1.0 molukg. The freezing point depression of the solution was determined to be 13.2 °C. What is the van't Hoff factor for acetic acid dissolved in cyclohexane? Is acetic acid an electrolyte when it is dissolved in cyclohexane? Explain. Kre20 °C/m...
Why does acetic acid form ions when dissolved in water but not when it is in the pure (glacial) form? Why or why not?
A monoprotic acid, HA, is dissolved in water: HA- The equilibrium concentrations of the reactants and products are [HA] 0.100 M [H1- 2.00 x 104 M A1-2.00x10-4M Calculate the value of pKa for the acid HA. Number
A monoprotic acid, HA, is dissolved in water: HA <------> H+ +A- The equilibrium concentrations of the reactants and products are [HA] = 0.280 M [H ] = 2.00 × 10–4 M [A–] = 2.00 × 10–4 M. Calculate the value of pKa for the acid HA.
1) Calculate the pH of the 1L buffer composed of 500 mL of 0.60 M acetic acid plus 500 mL of 0.60 M sodium acetate, after 0.010 mol of HCl is added (Ka HC2H3O2 = 1.75 x 10-5). Report your answer to the hundredths place. 2) Calculate the pH of the 1L buffer composed of 500 mL 0.60 M acetic acid plus 500 mL of 0.60 M sodium acetate, after 0.010 mol of NaOH is added (Ka HC2H3O2 = 1.75...
