When a buffer is used in an experiemnt does the buffer action last over the entire pH range? Why or why not? Please explain. What requires more acetate buffer to be used to reach the equivalence point a strong base or a strong acid? Please explain.
Now they have been tasked to make a 200 ml 0.15 M Tris buffer (pH value is not necessary to answer the questions below!), however, they found that in the chemical cupboard there is only Tris base (Tris-Cl-) powder but the container with weak acid powder is empty. The cupboard does, however, also contain bottles of strong bases and strong acids. i) explain how they can generate a functional buffer although they lack the Tris-HCl weak acid powder. Hint: explain what is necessary to obtain a functional buffer system? Here we do not ask for calculations but for a conceptual account on how the buffer can be made with only the Tris base as starting material. (Less than 150 words) ii) Calculate in grams (g) to three decimals precision the mass of Tris base (Tris-Cl-) powder that is required to generate the desired buffer.

Reorder the following steps to the correct order of preparing a buffer. 1.Weigh out the calculated dry reagents into a beaker and dissolve them with deionized water only up to 70% capacity of the total volume. 2.Use an acid or a base to adjust the pH of the solution to the required pH level. 3.Calculate the mass required to prepare all the dry reagents, specific for concentration and volume. 4.Adjust the volume of the solution to the total volume required for the buffer with deionized water.
Build a titration curve for the following scenarios. Make sure to label your accesses and anyother appropriate pieces of data. Each curve should have a minimum of 4 data points, but youcan use the following to help structure your curvea) Initial pHb) pH at Veqc) pH=pka (if applicable)d) pH when excess titrant is addede) Additional pH point near Veq for Strong Acid/Strong Base titrations (in order to see thesteepness of the slope) OR additional pH point in buffer zone for titrations with a Weakcompound.
