How would you make a buffer? A) mix the components together with large excess of the weak acid B) mix the components together with a large excess of the salt of the weak acid C) mix the components together in about the same mole ratio D) none of the above How would you make a buffer?

fFr a good buffer the pH of buffer should be near to PKa of the weak acid.
To get pH equal to PKa the the moles of weak acid and its salt should be same.
so C) mix the components together in about the same mole ratio
