Solutions of sodium acetate and acetic acid are combined in equal volume to produce a buffer. Identify the combination that will produce the buffer with the highest buffer capacity. Select one: a. 0.01 M CH3COOH , 0.1 M CH3COONa b. 0.1 M CH3COOH , 0.1 M CH3COONa c. 0.1 M CH3COOH , 0.01 M CH3COONa d. 0.01 M CH3COOH , 0.01 M CH3COONa

Answer asap need to be answered 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.
