The following pictures represent initial concentrations in solutions that contain a weak acid HA (pKa = 6.0) and its sodium salt NaA. (Na+ ions and solvent water molecules have been omitted for clarity.)

. (b) Draw a picture that represents the equilibrium state of solution (1) after the addition of two H3O+ ions.

Hello everyone today. We have the following question. The following representations of the initial concentrations of a weak acid H. A. With the following P. K. And it's potassium salt cay representation of the equilibrium state of solution to upon the addition of one sodium ion. And the potassium of water molecules were omitted for clarity. So when we add one hydrogen to solution to hear the conjugate acid or the conjugate base a minus is actually going to react with this acid there to neutralize the added acid. So that's gonna look like this. We're going to form that acid and that water. So initially I say initially our solution to contains three molecules of our acid or H. A. And three molecules of our conjugate base. But after we added an additional hydro ni um we're going to use another contact base to add in another acid. So we're gonna go from three Of our acids to four. We're also going to go from three of our conjugate bases to two of our conjugate bases. And so we need to look for representation that has this and if we look at our options, answer choice D. Best represents this and so with that we have answered the question overall, I hope this helped. And until next time
