Question

You make a solution by dissolving 0.0010 mol of HCl in enough water to make 1.0 L of solution.

Explain how two different volumes of your original HCl solution can have the same pH yet contain different moles of H3O+.

(Select all that apply)

-The two different samples contain the same numbers of moles, because they came from the same stock solution

-The two different samples always have the same concentration of HCl.

-There is no way this could be true.

-When the samples have the same number of moles of HCl, their pH must be the same.

-The two different samples always contain the same number of moles, even if they have different volumes.

-The two different samples contain different numbers of moles, because they have different volumes.

-The two different samples have different concentrations of HCl.

-When the samples have the same concentration of HCl, their pH must be the same.

-The two different samples always have the same concentration of HCl.
