Homework #1 10069 10-17-17 due date: 10-19-1. Calculate the pH of acetate buffer (3.0 Macetic acid and 3.0 M sodium acetate in 1.0 L) after the addition of 0.20 mol of NaOH Ka (acetic acid) = 1.8 × 10-5
D. Consider a buffer system prepared from 1.0 M acetic acid (HC2H,02) and 1.0 M sodium acetate (NaC2H,02). The Ka of acetic acid is 1.7x10 What is the pH of 1.0 L of this buffer, after 15.0 mL of 0.65 M HCI has been added?
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...
