My recent project
Hello everyone! I want to apology (again) for not writing in a loooong time but it was because I had another project for my English...
Adding Strong Acids or Bases to Buffer Solutions
For every mole of H3O+ added, an equivalent amount of the conjugate base (in this case, F) will also react, and the equilibrium constant...
Adding Strong Acids or Bases to Buffer Solutions
Good. Now let's see what happens when we add a small amount of strong acid, such as HCl. When we put HCl into water, it completely...
Adding Strong Acids or Bases to Buffer Solutions
Now that we have this nice F/HF buffer, let's see what happens when we add strong acid or base to it. Recall that the amount of F- in the...
Selecting proper components for desired pH
For the weak base ammonia (NH3), the value of Kb is 1.8x10-5 , implying that the Ka for the dissociation of its conjugate acid, NH4 + ,...
Selecting proper components for desired pH
Buffers function best when the pKa of the conjugate weak acid used is close to the desired working range of the buffer. This turns out to...
General ideas about buffers
If base is added: HF(aq)+OH−(aq) ⇌ F−(aq)+H2O(l) In this reaction, the conjugate acid, HF, will neutralize added amounts of base, OH, and...
