I am trying to replicate a pre-made calibration solution for measuring sulfur conent. Though I thought it seemed simple enought I have failed or my means of measuring have. I need to create a 100 ppm standard solution of sodium hydrogensulfie in water. Before I go to the lenghs to find a problem with my form of measurement  (aspiration in search of free SO2 and a autotitrater meathod) I wanted to know that my solution I was attempting to set as my standard is correct. Would anyone be so kind as providing me with directions on make 1L of a 100 ppm solution in water of Sodium hydrogensulfite, Pka of 1.99 I beleive, molar mass 104.061 g/mol.

edit: not solution in water, it needs to be at a PH of 11, so most likely some concentration of NaOH to bring it to 11.

Thanks

1 ppm = 1 mg in 1000 mL.

Dissolve 1 g of sodium hydrogensulfite in 1 L of pH 11 NaOH to get a 1000 ppm solution, perform serial dillutions until you have reached the correct concentration.
