A mixture of 0.0500 moles of each of the following is prepared in 1.000 L of DI water: HCl (large Ka) CH3COOH, acetic acid (Ka = 1.8x10-5) C6H5OH, phenol (Ka = 1.6x10-10) 1. Account for all activity coefficients and for the changes caused by the solution having an ionic strength that should not be neglected by including the appropriate activity coefficients, determine the concentrations of the species listed below at equilibrium in the solution: HCl, Cl-, H3O+, CH3COOH, CH3COO-, C6H5OH,...
a. Using the initial concentration of CH,COOH (from Problem 3) and the equilibrium concentration of H,0 calculated (from Problem 4), complete the reaction table for vinegar. Ignore the column under H:O() (shaded in gray). Don't forget to write a sign (+ or -) for the "Change” row entry. (9 pts: each entry is 1 pt.)

please help l, will rate! thabk you!!
Why does a solution of a weak acid and its conjugate base act as a better buffer than does a solution of the weak acid alone? The presence of both the acid and the base provides a significant concentration of both an acid and a base, making it harder to change the pH A solution of a weak acid alone has no base present to absorb added acid. The presence of both the...

A) The Ka of a monoprotic weak acid is 2.29 × 10-3. What is the percent ionization of a 0.129 M solution of this acid? I got 104.8% which I know is impossible. B) The Ka value for acetic acid, CH3COOH(aq), is 1.8× 10–5. Calculate the pH of a 2.40 M acetic acid solution. C) Calculate the pH of the resulting solution when 4.00 mL of the 2.40 M acetic acid is diluted to make a 250.0 mL solution. I...
3. Acetic acid, (CH3COOH) is the component in vinegar that gives it its acidity. It is a weak acid and only partly ionizes when mixed with water according to the following chemical reaction: ????3???????? + ??2?? ? ??3??+ + ????3??????- Write down the expression for the reaction quotient when acetic acid is mixed with water as shown above. if at equilibrium the concentration of CH3COOH is 0.5 M, CH3COO- is 0.4 M and H+ is 1.9 x 10-5, calculate the...
