iment in which 36.6 grams of BeSO4 is needed, but the only jar of reagent in the lab is labelled beryllium sulfate tetrahydrate. How many grams of the hydrate must the student weigh out in order to get the desired amount of the anhydrous compound?
ric acid. Titration of 11.3 mL X with 0.119 M silver nitrate required 78.2 mL of the latter. The resulting precipitate, containing a mixture of Ag2CrO4 and AgCl, was dried and found to weigh 1.420 g. How much 0.142 M sodium hydroxide should be used to neutralize 11.3 mL solution X?
acid. Titration of 13.6 mL X with 0.139 M silver nitrate required 40.7 mL of the latter. The resulting precipitate, containing a mixture of AgBr and AgI, was dried and found to weigh 1.260 g. How much 0.117 M sodium hydroxide should be used to neutralize 13.6 mL solution X?
