I attached a pic of the buffer and itâs pka and ph .can you just calculate the mass of this buffer needed to make 100.0ml of a 0.100M sln
Assigned buffer pH: pk, of the chosen weak acid or weak base: Question: Is your chosen compound an acid or a base? Ask if you are unsure. Weak Acid (or conjugate Weak Base (or conjugate Table 1 acid) base) Names of conjugate acid / base acetic acid Formula of conjugate acid / base Do you need to use HCl or NaOH to make the buffer (state which)? Ex: Let's say your assigned compound is trimethylamine, (CHy) N), which is a base. Its conjugate acid is called trimethylamine hydrochloride, (CH,),N HCI). So these are the names and formulas that you enter. Since it is a weak base, you need to add the strong acid HCI to make a buffer from a weak base.
