If 27.5 mL of 5.7 multiplied by 10-2 M HNO3 is added to 20.0 mL of 2.2 multiplied by 10-2 M HNO3, what is the pH of the solution?
If 12.5 mL of 8.6 multiplied by 10-2 M NaOH is added to 32.5 mL of 6.0 multiplied by 10-4 M NaOH, what is the pH of the solution?
moles first HNO3 = M x L = ??
moles second HNO3 = M x L = ??
molarity of final solution = total moles/total volume.
Since HNO3 is a strong acid (100% ionized) the pH = -log(H^+) and (H^+) (HNO3)
