Atp

[KathChem82]

if the mitochondrial membrane potential were 70 mV, as is common for other membranes, how much ATP could be synthesized from the transport of 4 moles of H+? assuming that the pH difference remains the same.

1. Barium hydroxide furnishes two moles of hydroxide in solution for each mole of barium
hydroxide that you start with, and HCl donates one mole of protons/mole of acid. Thus the
concentration of [OH-] = 0.0800 M. Since
equivalents of acid = equivalents of base
(X mL) (0.0800 M) = (15.0 mL)(0.100 M)
and X = 18.75 mL.
2. Sulfuric acid furnishes two moles of protons for each mole of acid. Thus the concentration of
[H+] = 0.500 M. Since moles of [H+] = moles of [OH-],
(X mL)(0.500 M) = (38.40 mL)(0.200 M) and X = 15.4 mL.
3. moles of HCl = moles of NaOH = 0.0125 moles
Molecular weight of NaOH = 40.0g, Weight of NaOH required = 0.50 g
4. This is a strong base which dissociates completely in solution.
[OH-] = 0.037M; pOH = 1.43; pH = 12.57
5. [H+] = 0.030, pH = 1.5
pOH = (14-1.5) = 12.5 [OH-] =3.3 x 10-13
6. (a) [H+] = 0.05 M pH = 1.3
(b) [H+] = 1.2 x 10-4 pH = 3.9
