Learning Targets:

I can explain how an acid can be weak in terms of "dissociation equilibrium".
I can write the the acid dissociation constant, K_a, for a weak acid.
I can use an ICE table to solve for [H⁺] or K_a for an aqueous solution of a weak acid.
I can calculate the pH of a weak acid using an ICE table.
