Calculate a sample for the preparation of 1000 ml of a titrated solution of ammonium thiocyanate (0.1 mol/l). How many ml of a solution of silver nitrate (0.1 mol / l) with K 1.0000 must be taken to set the correction factor for the molarity (K) of the ammonium thiocyanate solution so that 20.00 ml of titrant is used for titration? Mm. ammonium thiocyanate 76.12. Mm. silver nitrate 169.87.
