Question

1.0 x 10^-4 M Solution of HNO3 has been prepared for a laboratory experiment. Calculate the [H+] of this solution.

Answer 1

To determine the concentration of [H+] ions in the solution, it is important that we know the dissociation reaction of the solute. For this case, it would be

HNO3 = H+ + NO3-

Therefore, there is 1:1 ratio between HNO3 and H+ ions. The concentration of the ions would be the same as the solute which is 1.0x10^-4 M.
