WebBuffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid or a weak base plus a salt of that weak base. For example, a buffer can be composed of dissolved acetic acid (HC 2 H 3 O 2, a weak acid) and sodium acetate (NaC 2 H 3 O 2, a salt derived from that acid). WebHaving equal amounts of a weak acid and its conjugate base is a good buffer solution. Let's see what happens to the buffer solution if we add in a small amount of acid. So here I'm drawing in an H+ ion, and let's think about adding this H+ ion to our buffer solution.

WebWe know that we need to create 100.0 mL of buffer with a total concentration of 0.100 M: 100.0mL × 1L 1000mL × 0.100mol 1L = 0.0100mol Thus, we need 0.0100 moles total of both buffer components. We can set up the following two equations: mol(HCO2Na) + mol(HCO2H) = 0.0100mol mol(HCO2Na) / mol(HCO2H) = 1.16 or mol(HCO2Na) = 1.16 × …
