WebbI need to find the pH after 0.0015 mol of N a O H is added to 0.5 L of the solution. I started by converting everything to moles, writing out an equation for H A and O H X − reacting to make H X 2 O and A X −, getting 0.0985 mol of H A left after all the O H X − was used up, and 0.015 mol of A X − produced. At that point I got a bit stuck.
