web.pdx.edu(1) Calcium stock solution: Accurately weigh out about 0.252 g (to 0.001 g) of dry primary standard calcium carbonate (CaCO 3, FW=100.087). Rinse into a 100 mL volumetric flask with a few milliliters of deionized water. Dissolve in a minimum amount of 6 M HCI (a few mL) then dilute to the mark with deionized water and mix thoroughly.
