CREATE A SCHEMATIC DIAGRAM USING THE PROCEDURE: Weighing of standard reagents 1. Make an improvised weighing dish for solid samples (i.e. aluminum foil). Put the foil inside the analytical balance. 2. Press TARE. 3. Weigh accurately 0.4000 grams of NaCl powder in the foil. The reading of the weight must not exceed + 0.0030 g. Note that unused or excess chemicals should never be returned to the stock bottle. 4. Close the balance glass door. Note the actual weight of the NaCl powder that is reflecting on the analytical balance. 5. Transfer carefully the contents in a 150-ml beaker.
