Suppose you were to weigh out exactly 5 times the mass of sodium acetate used in buffer A (.200g) and dissolve this in .25 M acetic acid to make another buffer. How would the theoretical pH of this buffer differ from your other buffers?

Please see the attached picture for the complete answer.

Explanation:

Compound with sulfer  is bright red 

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
