Buffer 1 will be 100ml of 0.25 M acetate buffer pH 5.0
1. Write out the chemical equation for this buffer. Identify which species is the conjugate acid and which is the conjugate base.
2. For buffer 1 calculate the ratio of the base to acid using the Henderson-Hasselbach equation.
3a. Calculate the concentration of the conjugate acid and conjugate base in this buffer. (hint: the total concentration of this buffer is 0.25 M i. e. [acid] + [base] = 0.25 M) Calculate the concentrations in mM to zero decimal places. To convert numbers to mM from M, multiply by 1000.
3b. Using the Henderson-Hasselbach equation check that these ratios are correct.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
