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.
A 1.00 L buffer solution with pH = 4.74 is composed of 0.30 mol acetic acid and 0.30 mol sodium acetate. A) Determine the pKa of acetic acid B) If 0.030 mol of NaOH is added, determine the pH of the solution
Your task is to prepare a buffer solution of 1.00 L of 0.250 M acetic acid and solid sodium hydroxide. Start by writing the equation for the reaction that will form the buffer (hint: you must have both acetic acid and acetate ion in the solution; where will the acetate ion come from? Neglecting the volume change on addition of NaOH (MM 40.0 g/mol), what mass is required to produce a buffer of pH 3.75? What pH will the buffer...

Calculate the pH of 1.00 L of a buffer that is 1.00 M in acetic acid and 1.00 M in sodium acetate after the addition of 0.150 mole of NaOH.
A 1.00-litre buffer solution is made up containing 0.100 mol acetic acid and 0.200 mol sodium acetate: what is its’ pH? Then, 0.0500 mol of HCl gas is bubbled into the solution (assume no change in volume): what is the new pH? Data: pKa for acetic acid = 4.76
please solve and show work! A buffer contains 0.50 M CH3COOH (acetic acid) and 0.50 M CH3COONa (sodium acetate). The pH of the buffer is 4.74. What is the pH after 0.10 mol of HCI is added to 1.00 liter of this buffer? A.5.57 B.4.74 C.4.38 D. 4.92 E.4.57
A buffer formed from 20.0 mL of 0.120 M Acetic acid (CH3COOH) (pKa = 4.74) and 12.0 mL of 0.200 M sodium acetate (CH3COONa). What is the pH of this buffer after addition of 0.0001 mol of HCl?
A buffer solution contains 0.11mol of acetic acid and 0.14mol of sodium acetate in 1.00 L. What is the pH of this buffer? What is the pH of the buffer after the addition of 2
=Assume you have prepared 100.0 mL of a buffer solution using 0.400 mol of acetic acid (pKa = 4.74) and 0.400 mol of sodium acetate. The pH of this buffer solution is initially 4.74. After preparing this buffer solution, you added 55.0 mL of a 1.10 M NaOH solution to your buffer to see what would happen. What will the pH of this new solution be?
