To make a buffer using a weak base, we need to mix it with its conjugate acid. For example, to make a buffer using NH 3, we would need to add its conjugate base NH 4 + by adding ammonium ion mixed with the negligible conjugate base of a strong acid. So, we could add NH 4 Cl, NH 4 Br, NH ... 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 × … list of volunteer work ideas
