Say, for example, that you had prepared a Buffer C, in which you
mixed 8.203 g of sodium acetate, NaC2H3O2, with 100.0 mL of 1.0 M
acetic acid.
a. What would be the initial pH of Buffer C?
pH of Buffer C = 4.74, pH of Buffer B = 4.74
b. If you add 5.0 mL of 0.5 M NaOH solution to 20.0 mL
each of Buffer B and Buffer C, which buffer’s pH would change less?
Explain.

Lab 5: Buffers Data analysis 1. Write reaction equations to explain how your acetic acid- acetate buffer reacts with an acid and with a base, respectively. 2. Buffer capacity has a rather loose definition, yet it is an important property of buffers. A commonly seen definition of buffer capacity is: "The amount of Hor OH that can be neutralized before the pH changes by one unit." Use your data to determine the buffer capacity of Buffer A and Buffer B....

D. Buffers 1. A buffer solution was made by dissolving 10.0 grams of sodium acetate in 200.0 mL of 1.50 M acetic acid. Assuming the change in volume when the sodium acetate is added is not significant, estimate the pH of the acetic acid/sodium acetate buffer solution. The K, for acetic acid is 1.8 x 105. 2. Calculate the pH of a buffer solution that initially consists of 0.0400 moles of ammonia and 0.0250 moles of ammonium ion, after 20.0...

If 5.00mL of a 1.0 M NaOH solution is added to one of these buffers, what would be the resulting pH after addition? ---Had to make a IACE table and what I got was pH=5.20 4: What is the total volume of NaOH (1.0 M) you...
