An aqueous solution contains 0.5 mM HEPES (below left) and 0.5 mM HEPES sodium salt (below right). The pKa of the protonated form of HEPES is 7.5. What is the pH of the solution?
Added by Elena H.
Step 1
The solution contains 0.5 mM HEPES and 0.5 mM HEPES sodium salt. HEPES is a zwitterionic buffer, and the HEPES sodium salt is its conjugate base. Show moreā¦

Consider a buffer solution containing 10 mM of the monovalent salt HEPES, pKa = 7.55. HEPES: 4-(2-Hydroxyethyl)piperazine-1-ethanesulfonic acid N-(2-Hydroxyethyl)piperazine-N'-(2-ethanesulfonic acid). 0.1 ml of 1 M H2SO4 is added to 100 ml of this buffer, which has an initial pH of 7.2. 7.1) What is the pH of this solution after it has come to equilibrium (long enough to come close)? (10') 7.2) What is the pH of this solution if there is no such buffer? (5') 7.3) What is the buffer strength of HEPES?
