Just one more question: so the volume doesn't change even after adding 0.200 L of nitric acid? Wouldn't it be different?

Oh, I see! Thank you =)

I'm not sure I'm understanding correctly - would the correct concentrations be 1.2 M and 1.3 M?

So this is what I ended up doing: 0.200 L of 1.000 M nitric acid was added, which means that 0.200 moles of nitric acid was added. Since it's a strong acid, it fully dissociates, meaning that there are 0.200 additional moles of hydrogen ions in the solution. Since there are more protons in the...

Does that mean there wouldn't be any carbonate ions left in the solution?

Oops, that is a typo =P Apologies! So if I add HNO3, it would dissociate, creating more H3O+. And the addition of hydronium ions would shift the equilibrium to increase the concentration of HCO3-, which decreases the concentration of CO32-. Is that right?

Homework Statement What is the pH of a carbonate buffer solution prepared by mixing 1.500 mol Na2CO3 and 1.000 mol NaHCO3 and adding water to make a 1.000 L solution? (pKa of (HCO3)- is 10.32) A 200.00 mL sample of 1.000 M nitric acid was added to the buffered solution above. What is the...
