Another phosphate buffer system known as the Phosphate buffer system operates in the internal fluids of all cells. This buffer solution is composed of dihydrogen phosphate ion (HPO4), a weak acid, and hydrogen phosphate ion (H2PO42-), as its conjugate base. Draw an illustration of the mechanism of action of this buffer system when: a. A strong acid (which produces H3O*) is added to the buffer. b. A strong base (which produces OH-) is added to the buffer.

1. Another phosphate buffer system known as the Phosphate buffer system
operates in the internal fluids of all cells. This buffer solution is composed of
dihydrogen phosphate ion (HPO4), a weak acid, and hydrogen phosphate ion
(H2PO42-), as its conjugate base. Draw an illustration of the mechanism of
action of this buffer system when:
a. A strong acid (which produces H30*) is added to the buffer.
b. A strong base (which produces OH-) is added to the buffer.
