3. A primary standard is a reagent that is extremely pure, stable, has no waters of hydration, and typically has a high molecular weight. One such stable standard, even though its formula weight is not high, is sulfamic acid, NH SOOH (formula weight 97.09 g/mol). How many grams of this salt will be required to titrate 50.0 ml of 0.15 M NaOH solution? NH3SOOH (aq) + NaOH(aq) - NH2SOONa (aq) + H2O (1) *1314-YEAR 2019-2020 11-12
