Question

For the following reaction: HA(aq) + H2O(l) ⇌ H+(aq) + A-(aq), Kc = 2x10-7 at 25oC...

For the following reaction: HA(aq) + H2O(l) ⇌ H+(aq) + A-(aq),

Kc = 2x10-7 at 25oC

The initial concentration of [HA] = 0.50M.  

What is the [H+] of the solution at equilibrium?

Hint: you can assume x is small in comparison to 0.5M.
