Question
PLEASE SHOW WORK The compound Tris (2-Amino-2-(hydroxymethyl)propane-1,3-diol) is an amine with the protonated form (ammonium ion) having the following pKa value: HTris + H +
PLEASE SHOW WORK
The compound Tris (2-Amino-2-(hydroxymethyl)propane-1,3-diol) is an amine with the protonated form (ammonium ion) having the following pKa value:
HTris+ H+ + Tris pKa = 8.07
a. Calculate the pH of a solution made by adding 0.040 moles of Tris to 250 mLs of de-ionized water.
b. Now suppose 0.020 moles of strong acid (HCl) is added to the solution from part a. Calculate the new pH (you may ignore dilution)
