Buffer Lab

You will be provided with 0.100 M acetic acid, solid sodium acetate, and a strong acid or base solution, and all of the equipment needed to perform this experiment

Assuming that Ka is 1.85*10^(-5) for acetic acid, by using the Henderson-Hasselbalch equation and

CH3COOH + H2O --- CH3COO- + H3O+

*** (pH 5.10 in this case)

*** ( Total concentration of acid/conjugate base is 0.0800)

Give full steps of the calculation, including the Henderson-Hasselbalch equation, C1V1 =C2V2, Formula weight of NaCH3CO2 is 83.0343 g/mol

Calculate

1. volume of acetic acid

2. mass of sodium acetate you require to prepare 250 ml buffer solution
