How would I make a 0.25M solution of sodium bisulfite?

Answer 1

Weigh a sample of NaHSO3 equal to 0.25 moles (moles = grams/molar mass), place the solid in a 1L volumetric flask, add some water and swirl until all of the solid has dissolved, then make to the mark with distilled water. Mix thoroughly. That will give you 0.25moles in 1 L which is 0.25 M.
